Problems solved by technology

[0006] Although the research and application of collectors for potash slime abroad have relatively mature technologies, the characteristics of foreign potash mines are clay-carbonate impurities that are insoluble in water, while illite and chlorite in domestic potash mines Sludge, montmorillonite, and kaolin are the main components of ore slime, so the above technologies are difficult to be directly applied in my country. It is very important to study the flotation desliming process suitable for the characteristics of ore in my country.

Embodiment 1

[0024] Prepare 1# floating mud agent: Add 5g kerosene into the container, add 2gMR-1 type kerosene emulsifier in proportion while stirring, and stir to form a uniform transparent solution without stratification or precipitation. Under the condition of stirring, slowly add water into the transparent solution. With the addition of water, the solution first turns into a white viscous shape. When the added amount reaches 10g, stop adding water and keep stirring for 15 minutes. After adding the remaining 30g of water, the solution begins to Thin, and then get a homogeneous white emulsion, which is the floating mud agent.

Embodiment 2

[0026] Prepare 2# floating mud agent: add 4.5g kerosene into the container, add 1.5g MR-1 type kerosene emulsifier in proportion while stirring, and stir to form a uniform transparent solution without stratification or precipitation. Under the condition of stirring, slowly add water into the transparent solution. With the addition of water, the solution first turns into a white viscous shape. When the added amount reaches 6g, stop adding water, keep stirring for 20min, add the remaining 24g of water, and the solution starts Thin, and then get a homogeneous white emulsion, which is the floating mud agent.

Embodiment 3

[0028] Prepare 3# floating mud agent: add 8.5g kerosene into the container, and then add 3g polyglyceride of fatty acid in proportion under stirring, and stir to form a uniform transparent solution without stratification or precipitation. Under the condition of stirring, slowly add water into the transparent solution, with the addition of water, the solution first turns into a white viscous shape, when the added amount reaches 10g, stop adding water, keep stirring for 30min, then add the remaining 40g of water, the solution starts Thin, and then get a homogeneous white emulsion, which is the floating mud agent.

[0029] Application of floating mud agent (potassium ore is deslimed by cyclone first, and then deslimed by flotation):

Abstract

The invention provides a fluid mud agent, which comprises the following components in parts by weight: 2.5-3 kerosene, 1 kerosene emulsifier and 15-20 water. The invention further discloses a technology using the fluid mud agent to remove the mud in potassium mineral, which comprises that a cyclone separator is firstly adopted to make the mud content in the mud-contained potassium mineral reach 5-15%, and then the fluid mud agent of the invention is then used to further remove the residual mud. The fluid mud agent and the mud removing technology has good mud removing effect on high mud-contained potassium mineral, can reduce the mud content to about 2%, reduce the influence of the mud on the subsequent production, and improve the yield of potassium ion while greatly reduce the usage of sylvite collecting agent.

Description

technical field [0001] The invention relates to a flotation agent, in particular to a floating mud agent and a mud-removing process for potassium ore containing mud. Background technique [0002] my country is a large potash consumption country, but it is also a country that is very scarce in potassium resources. With the rapid development of my country's potash industry, over-exploitation has resulted in the increase of muddy potash deposits in salt lakes year by year, and the continuous decline of high-grade potash deposits, resulting in The mineral extraction process is getting more and more difficult. At present, in Chaerhanmahai Salt Lake, one of the main distribution areas of potassium salt in my country, the high-grade potassium ore (potassium chloride 15%) is basically exhausted, replaced by lean ore with low grade and high mud content. This kind of lean ore is not only low in grade (potassium chloride < 8%), high in mud content (mud content 30-60%), but also has ...
