Pyrite Underground Mining Process

During the mining processes pyrite (FeS2) had been extensively mixed with air oxygen.During mining the water level drowning and increasing aeration zone cause intensive pyrite oxidation, which is the biggest groundwater pollution problem associated with underground mining.

What is Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Pyrite - Wikipedia

Pyrite oxidation is sufficiently exothermic that underground coal mines in high-sulfur coal seams have occasionally had serious problems with spontaneous combustion. The solution is the use of buffer blasting and the use of various sealing or cladding agents to hermetically seal the mined-out areas to exclude oxygen.

Separation Process of Chalcopyrite, Galenite, Sphalerite and Pyrite. 1. The Separation of Chalcopyrite and Pyrite. Method. It depends on the ore property, including the following two methods: 1.1 Preferential Flotation: This method is suitable for dense lump ores.

Mining equipment for Pyrite processing

Pyrite mineral processing. As a kind of mineral resource, pyrite plays an important role in many areas. There are two methods for pyrite mineral processing which are gravity separation and flotation separation. Gravity separation is often used for processing medium particle disseminated pyrite ore with good separation performances.

Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Small scale surface mining started in the 1970s until the start of large-scale surface mining in 1991, leading eventually to the start in 1994 of the CCV Cresson Project. Today, CCV is a low-grade, open-pit operation. Ore processing. The ore is treated using a valley-type, heap-leach process with activated carbon used to recover the gold.

Mining Operation - PorgeraJV

Mining in the open pit is undertaken on 10 meter high benches. When the material is too hard to be free dug, the rock is drilled and blasted with a range of drill patterns to suit the litholog. The Open Pit is a conventional truck and shovel operation and is serviced by a large modern mining fleet of 175t and 90t haul trucks, loaded by 200t and ...

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.

This process is continued until only heavy “black sands” (such as ilmenite, magnetite, and pyrite) and gold remain. The material is dried and the gold removed (perhaps after using a magnet to remove some of the black sand). Panning is slow, backbreaking work, but in experienced hands there is little or no loss of gold. See also placer mining.

The open pit mining will be an expansion by a small push back of the south eastern wall of the existing pit to recover the remnant shallow resource. The pit expansion will be mined as the last stage of production from the deposit, to avoid complication of simultaneously working above an operating underground mine.
