Flotation machine Flotation is the most widely used method in copper mine production. The copper ore pulp is stirred and aerated, and the ore particles adhere to the foams under the action of various flotation agents. The foams rise to form a mineralized foam layer, which is scraped or overflowed by the scraper.home - Seraphim,Copper ore is one of the most essential metal on the planet today, and it has been utilized by humans for millennia for a variety of reasons. Copper’s versatility of properties makes it ideal for a variety of industrial applications.Innovations: Introduction to Copper: Mining & Extraction,Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
