Jul 03, 2013 · On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if highgrade concentrates are desired. This paper addresses some of these with examples on how technological developments enhanced the feasibility .
In June 2019, development began of a second pit the Oriental pit targeting highgrade sulphide ore. Sulphide ore is treated in the flotation plant producing a coppergold concentrate. The tails from flotation are treated in the magnetite plant to produce a highquality, lowcost iron concentrate.
Part of this company's assets was a huge deposit of lowgrade ore that it could not afford to develop. Phelps Dodge bought Arizona Copper and merged it with its Morenci holdings in 1921, in exchange for 50,000 shares of capital stock. By 1925 business expansion was demanding record amounts of copper.
With the rising gold prices in recent years, it further stimulated the rapid development of gold mining industry. As the exhaustion of highgrade gold ore, researching on middlelow grade and refractory gold ore and strengthen the traditional gold recovery undoubtedly have become the main trend in .
