Embodiment 1

[0028] A kind of beneficiation method of particulate sulfur-oxygen mixed type copper ore in alpine region comprises the following steps:

[0029] Step 1. Grinding the raw ore to obtain a semi-autogenous grinding ore product, sieving the semi-autogenous grinding ore product to obtain the on-sieve pebbles and under-sieve pulp, and the above-sieve pebbles to return to the semi-autogenous grinding process Repeated grinding, the under-screen slurry enters the slurry pump pool;

[0030] Step 2: Add a certain amount of lime, vulcanizing agent, activator, collector HTB and foaming agent to the slurry in the slurry pump pool to classify the slurry in the slurry pump pool to obtain graded overflow and graded sand settling , the graded grit enters the ball mill for grinding to obtain a ball mill grinding product, and the ball mill grinding product is returned to the slurry pump pool for repeated classification, and the graded overflow enters the mixing tank for mixing and mixing;

Embodiment 2

[0035] A kind of beneficiation method of particulate sulfur-oxygen mixed type copper ore in alpine region comprises the following steps:

[0036] Step 1. Grinding the raw ore with a particle size grade of -160mm accounting for more than 80% of the total mass of the raw ore to obtain a semi-autogenous ore product with an ore concentration of 80-85%, and screening the semi-autogenous ore product The above-sieve obstinate with a particle size greater than 12mm and the under-sieve pulp with a particle size of -0.074mm in the contained ore accounted for 30-35% of the total mass of the ore contained in it were obtained. The above-sieve obstinate was returned to semi-autogenous grinding for repeated grinding. The slurry under the sieve enters the slurry pump pool;

[0037] Step 2: Add a certain amount of lime, vulcanizing agent, activator, collector HTB and foaming agent to the slurry in the slurry pump pool to classify the slurry in the slurry pump pool to obtain graded overflow and...

Abstract

The invention relates to a beneficiation method of particulate sulfur oxygen mixed copper ore in a high and cold area and belongs to the technical field of a copper ore beneficiation method. In orderto solve the problems that the target ore and a floating agent have bad action effect and low recovery rate in the beneficiation process of the sulfur oxygen mixed copper core in the high and cold area, the invention provides the beneficiation method of the particulate sulfur oxygen mixed copper ore in the high and cold area. The beneficiation method of the particulate sulfur oxygen mixed copper ore in the high and cold area comprises the steps of comminuting raw ore, performing high-concentration size mixing and dosing in a pulp pump pool, performing ore pulp grading, performing two-section reinforced roughing, performing three-time copper scavenging and performing three-time copper selection. Advanced preadsorption of the ore and the medicament is realized, the problems of bad action effect of the medicament, large use amount and instability of a mineralized foam layer are solved, the defects of low vulcanization efficiency and unfirm vulcanization film are overcome, the capturing ability of the copper ore is effectively improved, the flotation time of the ore difficult to float is prolonged and the selected copper recovery rate is increased. The beneficiation method provided bythe invention is particularly suitable for treating hard-to-select sulfur oxygen mixed copper ore in the high and cold area, so that the comprehensive recovery ability of valuable copper resources iseffectively improved.

Description

technical field [0001] The invention belongs to the technical field of copper ore beneficiation methods, in particular to a beneficiation method for particulate sulfur-oxygen mixed copper ore in alpine regions. Background technique [0002] Copper is an important basic metal that guarantees the construction of the national economy. The characteristics of my country's copper ore resources are complex, and there are few copper mines with millions of tons of copper metal reserves, and copper ores generally have low raw ore grades, fine particle size of useful minerals, and Due to the high degree of oxidation and the symbiosis of various minerals, the recovery rate of useful metals is often low and the comprehensive utilization rate of resources is low when conventional copper separation processes are used to treat such refractory ores. The copper oxidation rate in sulfur-oxygen mixed copper ore is generally 20-30%. The ore composition is complex, with both sulfur and oxygen mine...
