Embodiment Construction

[0043] This embodiment takes the crushing of the Moweitang laterite nickel mine in Myanmar as an example. Because Myanmar is located in Southeast Asia, it has a tropical climate and abundant rainfall throughout the year. A large part of the Myanmar nickel mine is in the form of nickel oxide, so it is muddy. Ore with a large amount and water content (especially in rainy season). The ore with high mud content contains 50% water, 13% ore, and 37% argillaceous minerals.

[0044] Please check image 3 , A method for crushing materials with high mud content, the method includes:

[0045] Step 1. Crushing: crushing the raw ore containing mud and viscous materials, and washing with washing fluid at the same time; wherein, the size of the ore after crushing is less than 20mm;

[0046] Step 2. Washing: Wash the crushed minerals with washing liquid;

[0047] Step 3. It includes:

[0048] Step 31, sieving and grading to divide into coarse particles on the sieve (with a particle size of 5-20 mm) ...

Abstract

The invention relates to a method for crushing a high mud content adhesive material, comprising the following steps: crushing: crushing mud-containing adhesive material raw ores while flushing by flushing liquor; washedore: using washedore liquor to wash the crushed ores; fineness classification: performing fineness classification into coarse grain ores and fine grain ores, and dump-leaching the coarse grain ores; hydraulic classification: classifying fine grain ores by a hydroclone into overflow and underflow, enabling the underflow to enter tank leaching operation after ore grinding and the overflow to enter a thickening tank; and thickening separation: performing thickening separation in the thickening tank and dividing into underflow and overflow, enabling the underflow to enter the tank leaching operation after ore grinding, enabling the overflow to go back to step 1 as flushing liquor or the step 2 as washedore liquor partially or completely.

Description

Technical field [0001] The invention relates to a mineral processing method, in particular to a method for crushing materials with high mud content. Background technique [0002] When using a jaw crusher to crush ore, if the ore contains less mud, the crushing is easy to proceed, and the material after crushing is smooth; if the ore contains more mud-containing minerals and the water content is also large, this The crushing of the first type of ore will become very difficult, and the ore cutting is not smooth. Especially in the south, this situation is more likely to happen in the rainy season. If this engineering problem cannot be effectively solved, the production of the enterprise will be very abnormal and the economic loss will be huge. [0003] For the crushing of argillaceous minerals, some commonly used solutions are as follows: [0004] 1. Self-grinding technology [0005] The mud is easy to be blocked, broken and screened, and it is difficult to use the conventional grindi...
