2 天前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 fertilizerIn another, the matte may be roasted to produce highgrade nickelTraditional nickel laterite processing techniques use large quantities of sulphuric acid at high temperatures and pressures, resulting in expensive waste treatment and disposal of the chemicals used in the extraction process Nickel laterites are becoming a priority for mining companies as traditional nickelUnlocking millions of tonnes of nickel CSIRONickel is commonly present in two principal ore types—sulfide or laterite Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al, 2006)Global trends and environmental issues in nickel mining

Nickel: smelting, producingMetalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impuritiesNickel Nickel is a silver metal with a slight golden tinge with the symbol Ni and is atomic number 28 Nickel occurs mostly in combination with sulfur and iron The commodity Nickel can only be economically mined from two types of ore deposits, the first one being laterites and the second being magmatic modity Nickel Everything you need to know aboutThe reduction of nickel occurs as a batch operation in the reduction autoclaves Here an autoclave is filled with the purified solution and a small amount of nickel powder Hydrogen is added under pressure and the nickel precipitates from solution, depositing on the nickel powder The autoclave is agitated to keep the nickel in suspensionHow Sherritt Refines Nickel
