It can realize the copper concentrate grading at 15.84%with a 87.04% recovery through the bulk flotation with Cu-S separation process.
Iron Ore Beneficiation Process
During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable ...

Since the introduction of hydrometallurgical process for copper in the late 1980s, it has been widely used in China, especially for copper-bearing materials that cannot be effectively recovered by conventional processing methods, such as waste rock from open-pit ore stripping and low-grade copper oxide ore. Hydrometallurgical process is the ...
COPPER Copper production - TU Delft
About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
Beneficiation of Iron Ores – IspatGuru
Apr 03, 2014 · Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB).
A Gravity-Flotation Beneficiation Case for Low-Grade ...
The flotation is a commonly used beneficiation method for copper ore beneficiation and purification, but for some low-grade copper ore beneficiation, flotation method needs high investment in equipment, but small profit, therefore it need to design a more appropriate beneficiation process according to the specific nature of the ore.
Preconcentration for Low Grade Copper Ore
There is copper oxide and copper sulfide for copper ore with main beneficiation method of floatation separation to gain the ideal beneficiation efficiency. However, many copper mines are not profitable to enrich by floatation separation. And other treatment has to be taken into consideration before floatation separation. Here is some preconcentration method for some low grade copper ore.
