Gold extraction by resin pulp method
The Gold Resin Adsorption Process
The gold resin adsorption process (GRAP) is a method used to extract gold from ore or concentrate. The process is based on the absorption of gold ions onto the resin. GRAP has a number of advantages over other methods of gold extraction. It is simpler, quicker an......
Nickel concentrate
Nickel ore
Nickel ore is an ore that contains nickel often found in nature and often enriched through industrial processes. Non-ferrous ores, ores of nickel, copper, zinc and lead, are collectively called sulfide ores. When nickel ore comes in contact with air and water, it forms nickel oxide, wh......
copper substitution precipitation
Introduction
Copper replacement precipitation is an essential process that is used as a coating technique. It is also known as metal plating or electroplating. It is a process of bonding metal ions to an object by passing an electric current through a solution containing a base metal. This techni......
