Stamp Milling Mineral Processing & Metallurgy

28/10/2016 The average duty of a miner’s inch in a gold stamp-mill is given by P. M. Randall as 12 tons of quartz if the head under which the water is supplied is 4 inches, and 15.88 tons if the head is 7 inches. This gives the proportion of the volume of water to that of ore as 11.1 to 1. This may be compared with the proportion of between 7 and 10 to 1 in Siberian placer working, and as much as 30, or even 50 to 1 in hydraulic mining.

Artisanal and Small-Scale Gold Mining Without Mercury

Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold
