Embodiment 1

[0029] Step 1. Weighing the high-sulfur bauxite to be desulfurized and crushing it for later use;

[0030] Step 2. Weigh sodium carbonate, water glass and copper sulfate respectively according to the mass / number ratio of 2.5:2.1:0.04, and set aside;

[0031] Step 3. Transport the high-sulfur bauxite weighed in step 1 to the mill for grinding. During the grinding process, add the sodium carbonate weighed in step 2 until the high-sulfur bauxite with a particle size of -0.074mm Bauxite accounts for 85-90% and is reserved for use. The mass ratio of sodium carbonate to high-sulfur bauxite is (2.5-4.5): 1000;

[0032] Step 4. Add the water glass and copper sulfate weighed in step 2 to the high-sulfur bauxite in step 3, stir for 30 minutes to make slurry, then add xanthate desulfurization collector and foaming agent to it for floating Select and harvest for 17 minutes, and reserve;

[0033] Step 5. The mixture processed in step 4 is subjected to two rough, two fine and one sweep op...

Embodiment 2

[0035] Step 1. Weighing the high-sulfur bauxite to be desulfurized and crushing it for later use;

[0036] Step 2. Weigh sodium carbonate, water glass and copper sulfate respectively according to the mass / number ratio of 3.0:2.5:0.06, and set aside;

[0037] Step 3. Transport the high-sulfur bauxite weighed in step 1 to the mill for grinding. During the grinding process, add the sodium carbonate weighed in step 2 until the high-sulfur bauxite with a particle size of -0.074mm Bauxite accounted for 85~90, spare;

[0038] Step 4. Add the water glass and copper sulfate weighed in step 2 to the high-sulfur bauxite in step 3, stir for 30 minutes to make slurry, then add xanthate desulfurization collector and foaming agent to it for floating Select and harvest for 20 minutes, set aside;

[0039] Step 5. The mixture processed in step 4 is subjected to two rough, two fine and one sweep operations to obtain the product.

Embodiment 3

[0041] Step 1. Weighing the high-sulfur bauxite to be desulfurized and crushing it for later use;

[0042] Step 2. Weigh sodium carbonate, water glass and copper sulfate respectively according to the mass / number ratio of 4.0:3.0:0.08, and set aside;

[0043] Step 3. Transport the high-sulfur bauxite weighed in step 1 to the mill for grinding. During the grinding process, add the sodium carbonate weighed in step 2 until the high-sulfur bauxite with a particle size of -0.074mm Bauxite accounted for 85~90, spare;

[0044] Step 4. Add the water glass and copper sulfate weighed in step 2 to the high-sulfur bauxite in step 3, stir for 30 minutes to make slurry, then add xanthate desulfurization collector and foaming agent to it for floating Select and harvest for 17 minutes, and reserve;

[0045] Step 5. The mixture processed in step 4 is subjected to two rough, two fine and one sweep operations to obtain the product.

Abstract

The invention discloses a high-sulfur bauxite desulfuration flotation activating agent and a desulfuration method. The activating agent is composed of, by mass, 2.5-4.5 parts of sodium carbonate, 2.1-3.7 parts of water glass and 0.04-0.1 part of copper sulfate. The desulfuration method includes the following processes of material weighing, ore grinding, size mixing, floatation, collecting and two-time-roughing two-time-concentration and one-time-scavenging work for obtaining products. The obtained products have high dispersity and selectivity, and the method can solve the problem that activation in mineral is relatively difficult effectively.

Description

technical field [0001] The invention relates to the field of non-ferrous metal flotation agents and metal neutralization and recycling, in particular to a high-sulfur bauxite desulfurization flotation activator and a desulfurization method. Background technique [0002] In the flotation process, effective activation of the target mineral is the key to obtain a good production index, and in the activation process, other gangue minerals or useful minerals in the mineral are usually activated by the activator, so that the According to the effect of good activation purpose minerals, the flotation production practice and theoretical research so far have proved that in the flotation process, especially in the separation flotation of polymetallic ores, the inhibitors and activation of various minerals are studied. , and trying to find various activators with special effects are of great significance to the effective separation of various minerals and the promotion of the developmen...
