Abstract

The gold mineral in a difficult to select gold mine has a relatively fine particle size, with an average particle size of 3.58 μ m. Mainly in the form of fine-grained embedding. The main gold bearing mineral is pyrite, with an average particle size of 32.80 μ m. 20 μ The content of particles below m is 33.84%, and the content of fine particles is relatively high. Due to the fine particle size of gold ore and gold bearing mineral pyrite, it belongs to difficult to select gold ore. The flotation recovery rate of conventional beneficiation process is about 80%. In order to further improve the flotation recovery rate of this difficult to select gold mine, experimental studies were conducted on the “intermediate ore re grinding flotation” and “intermediate ore coarse particle re grinding flotation” of the flotation intermediate ore, and based on the experimental research, on-site process flow transformation measures were proposed.
