Because of the different natures of the various types of gold ore, the methods of ore dressing are different, but generally, the gravity separation, flotation, amalgam and cyanide process, as well as the new processes in recent years such as resin in pulp process and heap leaching of gold are adopted. For certain types of ore,.
This product is made of imported high quality coconut shell as raw material,calcined by physical method,with good adsorption capacity ,high intensity and wear resistant,mainly used for Refining old and other precious metals by carbon in pulp (CIP) and heap leaching process. With high recovery rate in low grade ore, it the.
as raw material,firing by physical method,has the advantages of uniform. granularity, strong adsorption capacity, high abrasion resistance, which are. suitable for gold mining and production of modern ore, are mainly used to. extract gold with heap leaching or carbon in pulp method, to separate and. extract of precious.
Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction electrowinning (SX EW) for recovery of nickel.
