The Mining Process Waihi Gold

The Mining Process. 1. 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. Dump trucks haul the rock to the primary crushers in the open pit or toget price

Gold processing Britannica

Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value.

Gold processing Mining and concentrating

Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps forget price

Processing, smelting and refining gold World Gold

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysisget price
