Embodiment 1
[0021] The main minerals of a non-metallic mine in Shaanxi are potassium feldspar, albite, and quartz, with a content of 35%, 32%, and 31% respectively. There are also a small amount of magnetite, titanomagnetite, and maghemite in the ore ;The particle size of quartz is generally coarse, and a small part is metasomatized along the edge and middle of potassium feldspar, so it is not easy to dissociate completely; A small part of the particle size is extremely fine.
[0022] The ore feldspar and quartz separation process is as follows:
[0023] 1) Raw ore desliming: feed the crushed raw ore into a single-chamber free-settling grading box for sedimentation and desliming, remove the slime with a particle size of <0.01mm, and obtain raw ore grit products;
[0024] 2) Grinding of grit products: Wet grind the raw ore grit products obtained from desliming to a fineness of 45% and a grinding concentration of 50%;
[0025] 3) Magnetic separation: Feed the wet-milled ore pulp into the ...
Embodiment 2
[0030] The main minerals in the flotation tailings of a sulfur beneficiation plant in Gansu are quartz, plagioclase, biotite, and pyrrhotite, with contents of 77%, 20%, 1.5%, and 0.85%, respectively, and a small amount of chlorite, Magnetite, pyrrhotite; plagioclase argillization phenomenon is relatively serious, and the particle size distribution is wide, and the thickness is uneven; most of the quartz particle size is coarse and uniform, and a small part is metasomatized from the plagioclase core. tiny.
[0031] The ore feldspar and quartz separation process is as follows:
[0032] 1) Raw ore desliming: feed the crushed raw ore into a single-chamber free-settling grading box for sedimentation and desliming, remove the slime with a particle size of <0.01mm, and obtain the raw ore grit products;
[0033] 2) Grinding of grit products: Wet grind the raw ore grit products obtained from desliming to a fineness of 50% and a grinding concentration of 55%;
[0034] 3) Magnetic sepa...
Embodiment 3
[0039] The main minerals of a non-metallic mine in Guangdong are quartz, potassium feldspar, plagioclase, and a small amount of albite, biotite, magnetite, limonite, pyrite, garnet, etc. Quartz, potassium feldspar The contents of plagioclase and plagioclase are 54%, 39%, and 5% respectively. Potassium feldspar has a fine particle size and is partly muddy. The plagioclase has a wide particle size range, ranging from 2mm to 0.016mm; the quartz particle size is generally coarse.
[0040] The ore feldspar and quartz separation process is as follows:
[0041] 1) Raw ore desliming: feed the crushed raw ore into a single-chamber free-settling grading box for sedimentation and desliming, remove the slime with a particle size of <0.01mm, and obtain raw ore grit products;
[0042] 2) Grinding of grit products: Wet grind the raw ore grit products obtained from desliming to a fineness of 55% and a grinding concentration of 45%;
[0043] 3) Magnetic separation: Feed the wet-milled ore pu...
