Potosi Silver Mine, Australia

The Potosi underground mine is located approximately 2km to the north of the existing North Mine and is parallel to the main Broken Hill Line of Lode, in New South Wales, Australia. It includes two mining zones, known as Potosi North and Potosi Extended.

Owned and operated by Perilya, drilling of the Potosi Mine commenced in March 2007 but was kept under care and maintenance since September 2008 due to falling metal prices. Exploration studies continued through 2009 and confirmed the existence of minerals between the Potosi North and Potosi Extended zones.

The development was approved by the Broken Hill City Council in March 2010. The project was re-approved by the Perilya Board in February 2011, four years after the initial plans.

Development of the Potosi mine

"Potosi underground mine is located approximately 2km to the north of the existing North Mine in New South Wales."

Development work at Potosi began in 2011 and the production is expected to commence in late 2012. The project will mine at a rate of 450-500mt a year using the existing infrastructure and mining labour force of the Broken Hill Southern Operations.

The development cost of the Potosi silver mine is estimated at A$57.8m. Perilya will be funding the project from its existing cash reserves.

The Silver Peak deposit located adjacent to the mine is also being developed, along with the Potosi mine, as a combined project.

The development of Potosi / Silver Peak mine is expected to increase the production levels of the existing Broken Hill Mine by 30,000t in its first full production year and subsequently ramp-up to 45,000t.

Geology of Perilya's Potosi mine

The Potosi resource comprises narrow lenses present continuously from near the base of the pit to north of the Flying Doctor deposit located 10km north of the Broken Hill Southern Operations. The mineralised zone is 3km in strike length.

Potosi North and Potosi Extended represent 50% of the targeted mineralised zone along the strike.

Reserves at the New South Wales-based Australian mine

The Potosi Mine has inferred resources of 1.6 million tons (mt) at 14.1% of zinc and 3.4% of lead and 46 grams per tonne of silver (g/t). The Silver Peak mine has inferred resources of 390,000mt with 4.9% zinc, 9% lead and 77g/t silver.

Mining production methods to be used at the Potosi underground mine

Potosi mine was originally mined by Pasminco between 1996 and 2000 and was acquired as part of the Broken Hill prospect by Perilya in 2002. It was a 95m open-pit mine with an yield of 625,000t at 7.8% zinc and 1.6% lead.

"The development cost of the Potosi silver mine is estimated at A$57.8m. Perilya will be funding the project."

Potosi underground mine has a 1,400m decline developed from the previous open-pit mine. Its face is at 140m from the surface. A second decline will be developed adjacent to the Silver Peak mine and will be linked to the existing decline access.

Mining at Potosi will be undertaken through the modified Avoca method, wherein the ore is extracted in bottom-up sequence. A single crown pillar method will help achieve early ore production.

Stoping operations at the underground mine will be performed from a previously mined and now backfilled stope.

The current stope's width will be 3-15m and height 25m from the floor length. Waste rock will be used to backfill the stopes.

The ore will be transported in an underground truck to the surface, where it will be crushed in a portable crushing unit.

Potosi mine ore processing

The ore extracted at the Potosi mine will be processed in the Broken Hill Southern Operations concentrator. An access road will be laid to the Barrier Highway and the North Mine to truck the ore to the concentrator.

The capacity of the Southern Operations concentrator is 2.5mt. It is currently operating on a ten-day on / four-day off schedule and has idle capacity.

Processing of the Potosi and Silver Peak's crushed ore will bring the concentrator to full capacity and hence minimise the operating costs.

Coal processing equipments in South Africa

South Africa is not only rich in metal mining, but also rich in the nonmetal mining resources. For example, the coal reserve is the seventh of the world. Now South Africa is one the chief coal production countries, it is the fourth largest exporting country of coal and it is also the leader production country of liquid fuel made of coal. So coal crusher for sale in South Africa has big market. With more investors focus on the South Africa coal industry, Double has won more and more gaze from these investors.

Coal Processing Equipments

South Africa coal processing equipments offered by SBM are mainly jaw crusher, impact crusher, hammer crusher, ball mill and LM series grinding mills and feeder, screens and belt conveyors, etc.

Many producers produce coal aggregates, the coal crushing plants are able to satisfy their requirements. Many producers produce coal powders or process coal ash; in this case, the coal grinding machineries are very important.

Coal crusher plants

The commonly process of coal crusher plants in South Africa are similar with each other. Jaw crushers crush big coal lumps to small ones when they dig out from well or from deposits. It is really a easy work for Double jaw crusher. Actually, Double jaw crushers can be used to crush numerous mining ores and different stones, such as granite, marble, basalt, gravels, limestone, gypsum, clay, manganese ore, chrome ore, iron ore, gold ore, copper ore and zinc ore and so on.

As to the impact crushers, if the raw coal size is not very big, they can crush the lumps to small particles directly; if the raw coal size is big, impact crushers are used behind the jaw crushers. Though the application of impact crushers is wide, but impact crushers should used in crushing soft materials. If the coal deposit is small and producers just want to build one small coal production line in South Africa, Double hammer crushers are really good choices. Also, the output size of hammer crusher is quite small and adjustable, no other better machines are better than them in this function.

Coal grinding process

In the coal grinding process, ball mill and LM series grinding mills are widely used. It is well-known that many factors must be cared when producers grind coal powders, for example the inflammability. Double LM series grinding mill and ball mill well solve these problems. And they are really high performance and price ratio products.

Crusher plant maintenance

Convenient maintenance is so important in the quarrying crusher plant industry. Maintenance can be defined as working on something to keep it in a functioning and safe state and preserving it from failure or decline. Maintenance activities at quarries range from the maintenance of machines, equipment and vehicles to the keeping of roadways on site in good order, attending to such matters as providing edge protection and securing excavations.

It’s important to keep structural costs down, to design for ease of maintenance and operation, and to combine best practices with advances in fabrication and erection.

Best installation for crusher plant

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.Since the crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation.

The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with today’s tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor.

Basalt dressing plant

Basalt can be a dark-colored, fine-grained, igneous rock composed generally of plagioclase and pyroxene mineral deposits. It most commonly forms as a possible extrusive rock, such as a lava circulation, but can also kind in small intrusive systems, such as an igneous dike or possibly a thin sill. It has a composition comparable to gabbro.

Basalt is most frequently crushed by basalt killer and grinding machines for use just as one aggregate in construction jobs. Crushed basalt is used by road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields and will other purposes. Basalt is also cut into dimension stone. Thin slabs of basalt usually are cut and sometimes rubbed for use as ground tiles, building veneer, monuments and other gemstone objects.

Basalt Mining Machines

Basalt crusher adopt jaw crusher, impact crusher and mobile crusher in the basalt crushing plant and adopt ball mill, MTW ginding mill, MTW grinding mill, hammer mill and LM series basalt milling machine in basalt grinding plant. In basalt dressing plant contain spiral classifier, concentrator table, flotation machines, filter,concentrator and dryer.
To one complete basalt beneficiation production line,it may contain many of the machines.The final equipments configuration depends the practical demands and the design.

Basalt Beneficiation Flow

When blast or digged out from the underground or from the mountain, the excavator carry the basalt to the basalt crushing site and feed dump the raw basalt mining to the hopper. Then the vibrating feeder under the hopper feed the raw material to the basalt crushers. Usually the crushed aggregates size is 0~10mm when the basalt discharged from the basalt crushers and classified by the vibrating screens.

The the basalt grinding machines (such as the ball mill) will grind the basalt aggregates to sand size or smaller particles. After classified and cleaned by the spiral classifiers, the particles will be fed to the basalt flotation machines or concentrator table. Then the concentrator, filter and dryer will thicken and .dry the particle and high purity available mineral is produced. In the beneficiation process, dense separation is usually adopt one time concentrating process and the producer will sell it after that for low production cost.
