The gangue mineral surface inevitably enriches some copper ions, nickel ions and other metal ions when copper-nickel sulfide ore is ground and in the flotation process. These ions can activate the gangue minerals so as to influence the selective separation of valuable minerals and gangue minerals. This paper, based on the ore property, found that complexing agent LXA could make nickel grade increase to 7.88% from 6.32%, but the recovery rate reduced by 15.61%; complexing agent LXH1 could make nickel grade and recovery rate increase by 0.6% and 1.3% respectively by comparing the flotation effect in the presence of complexing agent EDTA, LXH1, sodium thiosulfate and LXA respectively.

Ore Mineralogy

The microbial microenvironment in heaps is strongly influenced by ore mineralogy. While laboratory studies on microbial activity under controlled conditions provide a good understanding how bioleaching organisms might assist in metal extraction, examination of the ore, its mineralogy and leaching chemistry offer additional valuable insights. Some examples are discussed and illustrated with data for a copper-nickel sulfide ore.

One of the stages of extracting gold and platinum from sulfide materials and circulating slags is the melting stage in ore-thermal and electric furnaces, where the melt is separated into matte and slag. Gold, platinum, and non-ferrous metals are concentrated in the matte. However, a significant portion of them ends up in the slag, which reduces recovery and increases environmental pollution. The main reason for their transition to slag is the flotation of sulfide droplets by gas bubbles, a significant proportion of which occurs during the decomposition of sulfides. Gold and platinum are associated with matte droplets during flotation. Evaluation of adhesion showed that it is large and comparable to the cohesion of these metals. One of the options to reduce the loss of valuable components is to add fluxes to the slag. The influence of calcite and fluorite on the distribution of gold and platinum over the melting products of copper–nickel sulfide materials (matte and slag) has been experimentally studied based on the above theoretical concepts of droplet flotation. When calcite was added to sulfide ore, there was a significant decrease in the sulfur content in the slag (more than 3 times). This, in turn, led to a decrease in non-ferrous metals in the slag by 2–3 times, with gold from 0.45 to 0.29 g/t and platinum from 2.15 to 2.06 g/t. The addition of fluorite to the mixture of copper–nickel matte and model slag (CaO/SiO2/Al2O3 = 40/40/20) significantly reduced the sulfur content and non-ferrous metals by 1.5 times, whereas gold was not found in the slag. The decrease in the number of sulfides in the slag is mainly because the listed additives reduce its viscosity. This leads to acceleration of the coagulation of sulfide drops, which are inevitably carried into the slag during flotation, and increases the rate of their settling to the slag–matte boundary, where they merge with the matte mass.
