A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of high-grade ore per year for 8 years. The deposit contains 0.12 ounces of gold per ton of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore
The following article will demonstrate the importance of modern screening technology in the mining sector and show how processing plants can be simplified and improved when the screening efficiency is increased. Examples are provided from applications in the processing of metal ores, iron ore and coal.
