Embodiment 1

[0025] Select the original ore of platinum-containing purple sulfur nickel ore in a certain place, the main mineral composition is purple sulfur nickel ore, pyrrhotite, tellurium platinum ore, arsenic platinum ore, magnetite, serpentine, chlorite, hornblende, pyroxene stone and calcite etc. Flotation was carried out according to the steps of the examples and the dosage of the reagents listed in Table 1.

Embodiment 1～5

[0026] Table 1 Dosage of Examples 1-5 (g / t raw ore)

[0027]

[0028] 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 xantha...

Embodiment 2

[0030] The raw ore is the same as in Example 1, the raw ore is firstly ground to -0.074mm to account for 70%, and water is added to adjust the slurry to a concentration of 33%. According to each ton of raw ore, 2000 grams of oxalic acid and 1000 grams of hydroxyethyl cellulose are added successively , 600 grams of copper sulfate, 200 grams of butyl xanthate and 100 grams of kerosene, stirred, and carried out a roughing flotation operation to obtain a roughing concentrate and a roughing tailing; Grind the ore to -0.043mm to account for 70%, add water to adjust the slurry to a concentration of 30%, and add 1000 grams of oxalic acid, 600 grams of hydroxyethyl cellulose, 500 grams of copper sulfate, and 200 grams of butyl yellow medicine and 100 grams of kerosene, stirred, and carried out the secondary roughing flotation operation to obtain the secondary roughing concentrate and the secondary roughing tailings; according to each ton of raw ore, add 200 grams of copper sulfate to th...

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 present invention involves a mineral method, which specializes in a flotal method of platinum mineral purple -sulfur nickel ore. Background technique [0002] Nickel is an indispensable important non -ferrous metal. Because it has excellent performance and is used to create stainless steel, high nickel alloy and alloy structure steel, it is widely used in industries such as military manufacturing, mechanical manufacturing, aerospace, new materials.In nature, nickel ore is mainly divided into two types: nickel sulfide and nickel oxide mines.Purple -sulfur nickel ore is one of the important nickel sulfide minerals, and some of them are rich in platinum elements. They are embedded in it with veins or magnets, or exist in the form of parcels. [0003] Purple -sulfur nickel ore [(Ni, Fe) 3 S 4 ] It is a stable intermediate product in a very limited oxidation environment, which is easily lost by oxidation.It changes from nickel -yellow iron ore or magnetic py...
