The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua ...

The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.

Zalta grinding aids lead to gains in grinding productivity by reducing cohesion and adhesion in the ore slurry. This decreases the viscosity and/or yield stress as the slurry moves through the ball mill, improving grindability by both cascading motion and freefall ball-striking motion. Key benefits include:

platinum ore in a batch mill of 5 dm3 and 175 mm internal diameter. One size fraction method was carried out to perform the experiment. Five mono-sized fractions in the range of 1.180 mm to 0.212 mm separated by √2 series interval were prepared. The fractions were milled at different grinding times (0.5, 2, 4, 15 and 30 min) and three

After grinding, separation and flotation, various additives are mixed with the slurry, such as olivine, quartzite, limestone and dolomite – depending on product specification and pellet type. The slurry is then filtered until it achieves a predetermined moisture content. When the concentration of the ore is complete, it is time for pelletisation.
