Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed or Native copper is simply the metal found unadulterated in nature Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselv
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore
Sep 27, 2019· Vulcanization Flotation Of Copper Oxide Ore Sep 27, 2019 In the copper oxide flotation, direct flotation method usually can not achieve better results Sulfuration flotation method is the main flotation method for treating copper oxide ore and mixed ore at home and abroad For malachite, azurite, and red copper
type of ore occurs in the same locations as other copper or Due to this, the economical evaluation of oxidized copper ore is important today In another study, sulphidising flotation of oxide copper-cobalt ores, using sodium hydrosulphide as the sulphidising agent, has been practiced in Katanga, Democratic Republic of Congo With sodium
ores are either treated through standard sulphide flotation, sulphidisation or flotation followed by acid leaching The performance of each of these process routes depends on the degree of oxidation as predicted by the proportion of acid soluble copper present in the ore Process parameters must be aligned to optimize the recovery and grade .
Hi I try to process galena and sphalerite ore in grade of 6% totally in flotation circuit In this ore, the oxide part is about 2 -25% so the overall recovery is low especially in sphalerite circuit How can I increase the recovery of oxide part t.
