2020/10/23Gold 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 2017/3/28Crush and mill the gold ore to dust like particles. Ore is put into the crusher, which breaks it up. Water is added during the process which, when mixed to the ore particles, creates a pulp. The ore in the pulp is then ground into smaller particles and pulverized into a

Extracting Gold

Next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp .

When the Stamp Mill was being used commercially the two tables in front of the batter boxes would be covered with mercury to catch the gold. We no longer use chemicals at our mine to process the ore. Due to the fact that oil makes gold float, we can not use oil on the Stamp Mill so we substitute oil with sorghum syrup we have to apply the sorghum syrup daily to the camshaft.

2020/10/21Traditionally, however, this type of mill machine has been used to mine gold, silver and copper. There are sketches by Leonardo da Vinci depicting a similar type of stamp mill for use by blacksmiths. A stamp mill, sometimes called a stamping mill, is constructed with a series of stamps arranged in what is normally a wooden frame.
