Embodiment 1

[0023] Using raw ore (containing Cu0.87%, S10.23%), the phase analysis of the raw ore shows that the distribution rate of copper oxide in copper minerals in copper minerals is 26.3%, and the rest is copper sulfide minerals. Copper sulfide ores are composed of brass Mainly mine. Other minerals are mainly pyrite, magnetite, etc., and main gangues are quartz, calcite, etc.

[0024] The flotation method of described copper oxide ore comprises the steps:

[0025] (1) Crushing and grinding: the crushed copper oxide ore is input into the grinding system for grinding treatment, and the ore after grinding is obtained. The ore particle size of the ore in the ore is -0.074mm. 80% of the total mineral products;

[0026] (2) Flotate the mineral material:

[0027] When the copper sulfide distribution rate in the raw ore is greater than 15%, the asynchronous flotation method is adopted, and the asynchronous flotation method includes copper sulfide flotation and copper oxide flotation, and...

Embodiment 2

[0032] Using the raw ore (containing Cu1.02%, S7.48%), the phase analysis of the raw ore shows that the distribution rate of copper oxide in copper minerals in copper minerals is 89.12%, and the rest is copper sulfide minerals. Mainly mine. Other minerals are mainly pyrite, magnetite, etc., and main gangues are quartz, calcite, etc.

[0033] The flotation method of described copper oxide ore comprises the steps:

[0034] (1) Crushing and grinding: the crushed copper oxide ore is input into the grinding system for grinding treatment, and the ore after grinding is obtained. The ore particle size of the ore in the ore is -0.074mm. 80% of the total mineral products;

[0035] (2) Flotate the mineral material:

[0036] When the distribution rate of copper sulfide in the mineral material is less than 15%, the synchronous flotation method is adopted;

[0037] In the first copper roughing, add lime 2000g / t raw ore, adjust the pH value of the pulp to 10, and then add 5000g sodium su...

Abstract

The invention discloses a flotation method of copper oxide ores. The method comprises the following steps: crushing and grinding ores, and performing floatation on the ores. Aiming at different distribution of the copper oxide ores, the flotation method adopts synchronous flotation and asynchronous flotation, so that the recycling rate of valent copper elements in the ores is improved, a plurality of types of flotation products can be easily produced and the value of the products is improved. Compared with traditional copper oxide flotation, the flotation method has the advantage that an efficient flotation capturing agent is formed by combining amyl-xanthate and nonyl hydroxamic acid, so that the recycling rate of whole copper and the quality of ore concentrate are improved. In order to strengthen a flotation process of the copper oxide ores, ethylenediamine phosphate and 2,5-dithiol-1,3,4-thiodiazole are used as floatation activating agents, so that the floatation efficiency can be improved, and meanwhile, the floatation recycling rate of copper oxide can be greatly improved.

Description

technical field [0001] The invention relates to a flotation method of copper oxide ore. Background technique [0002] my country's copper oxide ore reserves are abundant, which is an important part of my country's copper resources. In copper ore resources, in addition to the oxidation zone on the upper part of most copper sulfide deposits, there are also independent copper oxide deposits with huge reserves. Among the copper ores with industrial mining value, copper oxide ore and mixed copper ore are about It accounts for 25% of my country's copper resources. And the copper resource of my country presents the present situation of four more and four less: lean ore is many, rich ore is few; Easy mining and less ore dressing. With the continuous development and utilization of copper ore resources, the amount of easy-to-treat resources has been decreasing, and the proportion of refractory resources has been increasing. In particular, refractory copper oxide resources have a ce...
