The mining processes that occur worldwide are all very similar to each other in terms of exploration and extraction, how each mine deals with waste product varies. For an area to be mined, exploration geologists first assess the area to determine if there will be sufficient amounts of ore to make the area economically viable to mine, basically will there be enough ore to make profit after the

Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Mining – open pit and underground To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

The least common method in hardrock mining, block caving, is typically saved for lowgrade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn. The collapsed ore is hauled out the mine for processing

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry.
