Problems solved by technology

However, due to the low content of valuable minerals in primary platinum ore, gangue minerals occupy an absolute position, and some gangue minerals containing calcium, magnesium and phosphorus have good buoyancy, and enter the concentrate together with valuable minerals, resulting in the obtained platinum group concentrate. The ore grade is low, and it can only be regarded as a platinum group coarse concentrate product, which seriously restricts its utilization value

Embodiment 1

[0024] The raw ore is a primary platinum mine in Inner Mongolia, China.

[0025] (1) The raw ore is ground to -0.074mm, accounting for 80%, adding water to adjust the slurry to a pulp concentration of 27%, based on the weight of the ore, adding 2000g / t of sodium carbonate, stirring for 3 minutes, carboxymethyl cellulose 500g / t, Stir for 3 minutes, 240g / t butyl xanthate, stir for 2 minutes, 30g / t terpineol oil, stir for 1 minute, do rough selection; add 60g / t butyl xanthate, stir for 2 minutes, 10g / t terpineol oil, stir 1 minute, do a sweep; add 40g / t of butyl xanthate, stir for 2 minutes, pine oil 10g / t, stir for 1 minute, do a second sweep; add carboxymethyl cellulose 100g / t, stir for 3 minutes , carry out a beneficiation, add carboxymethyl cellulose 60g / t, stir for 3 minutes, carry out a second beneficiation, and obtain platinum group crude concentrate;

[0026] (2) Concentrate the platinum group rough concentrate to a slurry concentration of 45%, add water glass 100Kg / t ba...

Embodiment 2

[0029] The original ore is a primary platinum mine in a certain place in Heilongjiang, China.

[0030] (1) Grind the raw ore to -0.074mm to account for 75%, add water to adjust the pulp to a pulp concentration of 30%, add sodium carbonate 1000g / t, stir for 3 minutes, and water glass 2000g / t, stir for 3 minutes , 300g / t of butyl xanthate, stirred for 2 minutes, 30g / t of terpineol oil, stirred for 1 minute, and made rough selection; added 80g / t of butyl xanthate, stirred for 2 minutes, 10g / t of terpineol oil, stirred for 1 minute, Do a sweep; add 60g / t of butyl xanthate, stir for 2 minutes, 10g / t terpineol oil, stir for 1 minute, and do a second sweep; add 800g / t of water glass, stir for 3 minutes, and perform a sweep; Add 600g / t of water glass, stir for 3 minutes, and carry out second beneficiation; add 400g / t of water glass, stir for 3 minutes, and carry out three beneficiation to obtain coarse concentrate;

[0031] (2) Concentrate the rough concentrate to a pulp concentratio...

Abstract

A primary platinum ore beneficiation method is characterized in that rough platinum family concentrate is obtained after ore grinding and floatation are conducted on primary ore; the rough platinum family concentrate is heated and preprocessed through water glass; size mixing and floatation are conducted on the preprocessed rough concentrate to obtain platinum family concentrate high in platinum family metal grade. Compared with an existing primary platinum ore beneficiation method, the method has the advantages that valuable mineral and gangue mineral are thoroughly separated, and the concentrate grade is high. The method is suitable for primary platinum ore and particularly suitable for low-sulfur, low-platinum and low-palladium primary platinum ore.

Description

technical field [0001] The invention relates to a primary platinum ore beneficiation method, in particular to primary platinum ore with low sulfur content and platinum group. Background technique [0002] Platinum group metals have been praised as "the most important high-tech metal" since the 1980s, and are widely used in precious property, special function high technology, new energy, Environmental protection, catalysts and many other fields. [0003] The world's platinum ore resources can be divided into three categories: primary platinum ore; copper-nickel sulfide paragenetic ore with associated platinum group metals (not all nickel sulfide and copper ores are associated with platinum group metals); placer platinum ore. Their mineralization is related to ultrabasic and basic magmatic activities. At present, more than 90% of the platinum group metals in the world are extracted from basic rock copper-nickel sulfide deposits, mainly through the enrichment of copper-nickel...
