Gold extraction with BORAX for small-scale miners Rather Rich & Healthy than Poor & Poisoned Duration: 9:49. geusTUBE 968,237 viewsOre processing Waihi Gold,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
The definition of ore and waste rock depends on the cut-off grade. If the cut-off grade is one gram per tonne (1.0g/t) all rock with more than 1.0g/t of gold will be marked out as ore while all rock which contains less than 1.0g/t of gold will be marked out as waste rock. The cutoff grade can be as low as 0.75g/t.The Mining Process Waihi Gold,A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
Open-pit and underground mining result in the excavation of large volumes of rock to gain access to ore bodies. After the ore body is accessed, ore for processing is separated from the host rock on the basis of economic cutoff values. Rock of higher metal grade is processed, and Assaying analysis of ore samples Waihi Gold,Samples of rock from within the pit or from underground are sent to the SGS laboratory in Waihi to determine gold content. The data generated from assaying is used to map out which areas are suitable to process as ore and which areas are waste material to be used to build the waste rock embankment or to be used as backfill underground.

The refining procedure is then completed by placing the ingots (anodes) in vats containing a nitric acid solution and applying an electric charge. The ingot dissolves and the silver content is plated out on a cathode plate. The resulting silver crystal is removed from the cell, washed, dried, and melted into the desired shape as pure silver.Gold Refining Process Mineral Processing & Metallurgy,Refining using Sulphide of Antimony; Refining of Gold with the Cementation Processes.
