Encyclop dia Britannica, Inc. Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro

Nickel processing, preparation of the metal for use in various products.. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 C (2,647 F) and a face-centred cubic crystal structure, which gives

High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore. HPAL has been used since 1961 when it was
