Selective leaching of nickel from low-sulfur Ni-Cu
Before the conduction of leaching tests, the grinding characteristic of low-sulfur Ni-Cu matte was obtained from grinding tests which were performed in a laboratory stainless steel mill. 800.00 g matte sample was fed into the mill with 3.0 L tap water and Abstract: A process of the selective leaching of nickel from low-sulfur Ni-Cu matte at atmospheric pressure was described. This matte was obtained from high grade Selective leaching of nickel from low-sulfur Ni-Cu matte

Effect of grinding with sulfur on surface properties and floatability
The constant low flotation recovery of SiO2 in the whole process can be interpreted as the weak physical bonding of sulfur on SiO2 particle surfaces, instead of Base metal (Cu, Fe, and Ni) and trace element (Ag, Au, Co, Pd, and Pt) distributions between low-iron nickel mattes with [Ni]:[Cu] = 4 (w/w) have been stud Precious Metal Distributions in Direct Nickel Matte Smelting with Low

grinding of low sulphur mattes
Nickelcontaining mattes are desulphurized down to low sulphur levels (less than 1%) in a multistage process effected in a single converter vessel In the first stage, an oxidizing gas is blown into the molten matte to reduce the sulphur level to about 4 to 7% and in one or more subsequent stages, oxygen and a diluent are blown Crushing and grinding as if the material is brittle (friable), which is a property associated with high sulphur level mattes. For lower sulphur levels, where the matte is less amenable to milling, the cost of the milling produced from this reprocessing are low in sulphur and hence ductile, and not suited to processing by crushing and/orMETALS AND ALLOYS WATER SOLIDIFICATION A
