A USGS publication on the history of gold uses, gold mining, gold prospecting, assays and gold production.
Flotation separation process is one of the most important processes in ore beneficiation, so its use is extensive. It is widely used in concentrates selection of copper ore, nickel ore, iron ore, gold ore, limestone and other metal and non-metallic ore, with advantages of high efficiency, low energy consumption, high processing capacity, and reasonable economy, etc.
For Cheminova, Velgaard said that from an innovative molecule basis, the industry has not invested in the development of new flotation chemistries per se for the past three decades. Essentially, all its efforts have been focused on learning to understand better flotation collector responses to different mineralogy species, and tailoring collector combinations to enhance process performance for the more complex ores and difficult processing conditions the industry is experiencing.

It is difficult to remove the iron-bearing minerals in ultrafine feldspar particles by traditional methods, but leaching can achieve better results. The feldspar leaching reagent is not only beneficial to the decomposition of feldspar, but also can effectively remove the interlayer iron minerals on the surface of feldspar. Biological leaching has the advantages of simple operation and low environmental pollution.
