Embodiment 1～5

[0026]

[0027] The ore nickel grade is 0.32%, platinum grade is 0.55g / t. Grind the raw ore once to -0.074mm to account for 66%, add water to adjust the slurry to a concentration of 30%, and add 1000 grams of sulfuric acid, 1000 grams of water glass, 400 grams of copper sulfate, and 200 grams of butyl Xanthate and 100 grams of terpineol oil are stirred, and a roughing flotation operation is carried out to obtain a roughing concentrate and a roughing tailing; %, add water to adjust the slurry to a concentration of 26%. According to the raw ore per ton, add 800 grams of sulfuric acid, 1000 grams of water glass, 400 grams of copper sulfate, 150 grams of butyl xanthate and 50 grams of terpineol oil, stir, and carry out Secondary roughing flotation operation to obtain secondary roughing concentrate and secondary roughing tailings; according to each ton of raw ore, add 200 grams of copper sulfate and 100 grams of butyl xanthate to the secondary roughing tailings in turn, stir , ...

Abstract

A flotation method for platinum-mineral-containing violarite is characterized in that sulfuric acid, oxalic acid or citric acid is taken as a regulator and added into a palatinum-containing nickel mineral, water glass, sodium hexametaphosphate or hydroxyethyl cellulose is taken as gangue inhibitor, copper sulfate or lead nitrate is taken as an activator, butyl xanthate is taken as a collenting agent, terpenic oil, kerosene or diesel oil is taken as a foaming agent, and the effective enrichment of the platinum-mineral-containing violarite is realized by performing stage grinding, stage screening, rougher flotation, scavenging flotation and essential selection. The medicaments are reasonably added, ion composition in pulp and surface characteristic of the mineral are improved, preferential absorption of a target platinum mineral and the violarite is improved by the collecting agent, the recovery rate of the nickel is improved by 5 to 10 percent, and the content of a magnesium oxide deleterious impurity in nickel concentrate is reduced. The method is simple in process and easy to operate.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a flotation method of platinum-containing mineral purple sulfur nickel ore. Background technique [0002] Nickel is an indispensable and important non-ferrous metal. Because of its excellent performance, it is used to manufacture stainless steel, high-nickel alloy and alloy structural steel, and is widely used in military manufacturing, machinery manufacturing, aerospace, new materials and other industries. In nature, nickel ore is mainly divided into two types: nickel sulfide ore and nickel oxide ore. Violet sulfurite is one of the important nickel sulfide minerals, and it is partially enriched in platinum group elements, embedded in gangue minerals or magnetite, or exists in the form of inclusions. [0003] Purpurite [(Ni, Fe) 3 S 4 ] is an intermediate product that is stable in a very limited oxidative environment and is easily leached by oxidation. It is derived from the alterati...
