Benefits of technology

This patented inventors have developed an improved way to treat highly muted rocks containing sulfuric acid by heat treatment at very specific temperatures. By changing their characteristics such as size, shape, surface area, etc., they found out how these materials could behave differently when treated under different conditions. These changes resulted in better separation between them compared to other methods like froth flotations. Additionally, this innovative approach allows for more efficient mineral benefaction without requiring expensive upgrading processes. Overall, this new technique simplifies the overall manufacturing process while improving efficiency and reducing costs associated therewith.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the separation efficiency of green potasulfonate (CSP) while reducing costs associated therewith. Current methods involve expensive equipment like sand filters, centrifuges, settling basers, etc., making them impractical due to increased capital expenses involved. Additionally, current methods require complex operations involving multiple steps, leading to reduced throughput compared to traditional methods.

Embodiment 1

[0028] A processing method of high-mud potash rock salt ore is characterized in that the following steps are performed:

[0029] 1) Send the high-mud potassium salt ore crushed to a particle size of 0.15-0.3mm and dried in a vibrating fluidized bed at 200°C for 10 minutes into a fluidized roasting furnace, roast at 600°C for 20 minutes, cool to room temperature, and roast At the same time, the gas from the fluidized roaster is collected by the dust collector, sent to the electric heater by a high-temperature fan to increase the temperature, and then returned to the fluidized roaster to heat the ore powder to realize circulating air supply;

[0030] 2) The roasted material in step 1) is subjected to conventional rough flotation to obtain overflow and underflow, and the underflow is sent to the tailings dam;

[0031] 3) The overflow in step 2) is subjected to conventional fine flotation to obtain overflow and underflow, and the underflow returns to the rough flotation in step 2)...

Embodiment 2

[0034] A processing method of high-mud potash rock salt ore is characterized in that the following steps are performed:

[0035] 1) Send the high-mud potash rock salt ore crushed to a particle size of 0.15-0.3mm and dried in a vibrating fluidized bed at 300°C for 5 minutes into a fluidized roasting furnace, roast at 250°C for 90 minutes, and cool to room temperature to obtain Roasting material, at the same time, the gas from the fluidized roaster is collected by the dust collector, sent to the electric heater by a high-temperature fan to increase the temperature, and then returned to the fluidized roaster to heat the ore powder to realize circulating air supply;

[0036] 2) The roasted material in step 1) is subjected to conventional rough flotation to obtain overflow and underflow, and the underflow is sent to the tailings dam;

[0037] 3) The overflow in step 2) is subjected to conventional fine flotation to obtain overflow and underflow, and the underflow returns to the rou...

Embodiment 3

[0040] A processing method of high-mud potash rock salt ore is characterized in that the following steps are performed:

[0041] A) Perform conventional flotation desalination on high-mud potassium halite mines crushed to a particle size of 0.15-0.3 mm to obtain overflow and underflow containing sodium chloride, which will be sent to the sodium-salt dam, and sodium salt will be extracted through subsequent conventional processes ;

[0042] B) After the overflow of step A) is conventionally filtered and dried, it is sent to a fluidized roaster, roasted at 400°C for 40 minutes, cooled to room temperature, and the roasted material is obtained. At the same time, the gas from the fluidized roaster is dedusted. After the dust is collected by the dust collector, it is sent to the electric heater by a high-temperature fan to increase the temperature, and then returns to the boiling roaster to heat the ore powder to realize circulating air supply;

[0043] C) The roasted material in s...

Abstract

The invention provides a method for processing sylvite salt mine with high mud content. The sylvite salt mine with high mud content is subjected to flotation desalination, the overflow drying materials of the floated sylvite salt mine with high mud content are roasted at high temperature, and the physical and chemical properties of boulder clay substances in the sylvite salt mine with high mud content are changed, so that the salt mine is changed from fine particles to coarse particles and changed from hydrophobicity to hydrophilcity and sinks to enter ore pulp during floatation; and because the salt mine does not float up with foam, the salt mine is completely separated from potassium chloride grains which float up with the foam. The limitation that only low-mud-content green potassium raw ore can be processed in the traditional floatation processing technology is broken, and the problem that the mud cannot be separated from potassium chloride in the sylvite salt mine with high mud content is solved.
