Copper Recovery from Silicate

The copper concentrate obtained from flotation of the low-grade copper ore was treated by atmospheric leaching and high-pressure oxidative leaching processes. A maximum recovery (93.0%) of copper was obtained by high-pressure oxidative leaching in the water, whereas the copper recovery was lower than 12% in the sulfuric acid solution under atmospheric leaching conditions.

2020/7/1The copper mine industry is facing with the need to process low-grade ores using low-cost technologies to meet global demand unceasingly (Faramarzi et al., 2020). As an economical and environmental friendly method, bioleaching has been exploited to liberate metals, such as copper, iron and nickel, from low-grade ores in some mining area ( Panda et al., 2015 ).

Recovery of molybdenum from alkali leaching solution of

Abstract In order to extract molybdenum (Mo) from alkali leaching solution of low-grade Mo concentrate, static and dynamic ion exchange experiments were performed. The static experiments results indicated that the adsorption capacity of D201 resins reached 93.50% at pH 3.5, while the adsorption capacity of D314 resins was 95.47%. Therefore, D314 resin was adopted for further experiments. The

purification of copper by electrolysis metal extraction

Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper ores. These two methods avoid traditional mining methods of digging, moving and disposing of large amounts of rock - they make finite copper
