For example, the average iron grade of the iron ores in China is only around 33%, but the iron ore grade required for blast furnace smelting is at least 60% or even above 65%; the average copper grade of copper ore resources is 0.87%, while the copper ore grade required for copper smelting plant is usually 20%, and the Grade 5 copper …
Ore processing is a chain of processing applications which treats run of mine to firstly high-grade concentrate (concentration of ores) and then to the pure mineral or metal. The refined ore is used in manufacturing equipment and machinery in numerous industries, or is for sale in industry, commerce and consumer industries.
Metallurgical processing of metalliferous ores in general and gold ores in particular consists essentially of three stages. ... An ore containing 1% S will produce a mass pull of approximately 3% by weight to a flotation concentrate. If this ore also contains 1 g/t Au (for GSR =1), and 95% recovery to concentrate is achieved then 0.95g will be ...
