    The pressure oxidation of low-grade nickel sulfide concentrate with high iron sulfides content generates significant amounts of sulfuric acid that must be neutralized. This acid can be utilized to leach metal values from ores such as nickel laterites. The present study demonstrates the use of a low-grade nickel concentrate generated from Poseidon Nickel Mt Windarra ore to enable additional ...

    Jul 28, 2020· Diamond earrings are made of gemstone just as the name suggests. However, marcasite earrings are not made of real marcasite. Instead, the real material is pyrite. Real marcasite is brittle and easy to be eroded, while pyrite has the same color with marcasite and can be kept for a long time. So manufacturers choose pyrite as substitution. 2 - Price
