Problems solved by technology

For example, Gejiu potassium feldspar mine in Yunnan uses dry powder magnetic separation. Although it is easy to process, its technological process is old and old, with high processing cost, high energy consumption, low profit, low efficiency, monotonous products, and by-products cannot be comprehensively utilized. A little bit of wind, dusty, serious air pollution
Hubei potassium feldspar mine adopts flotation, its disadvantages are that chemical substances need to be added, the production cost is high, resource waste is serious, and environmental protection efficiency is poor

Embodiment Construction

[0012] Further describe the present invention by embodiment below:

[0013] Potassium feldspar is made of potassium feldspar in Qianxi County and Zunhua County, Hebei Province. The main mineral content (weight) is: more than 90% potassium feldspar, 2% iron mica, 5% iron, and 2% kaolin.

[0014] The specific process steps are as follows:

[0015] According to the conventional operation method of ore dressing, the potassium feldspar is crushed with a 500×700 crusher, and the crushed material is sent to a 135 hammer crusher for crushing again, and the crushed particles are sent to a 1.2×3.6-meter drum sieve for sieving, and the particle size under the sieve is Particles below 6mm are sent to a 1.83×7m mill to be ground into a fine powder of 20-200 mesh, and the fineness is selected according to user requirements.

[0016] Also includes the following process steps,

[0017] Mud washing: Send the 20-200 mesh material into a 1.2×4×40 spiral chute, add 6 tons of water per ton of ma...

Abstract

An iron-removing ore dressing technology for potash feldspar includes such steps as washing, breaking, sorting, concentrating, purifying, washing with sulfuric acid and sieving. It has high output (more than 90%), low content of Fe (less than 0.24%) and more by-products (silt, Fe, mica, Fe2O3 and Fe3O4).

Description

technical field [0001] The invention relates to a beneficiation process, in particular to a beneficiation process for removing iron from potassium feldspar. Background technique [0002] At present, the beneficiation methods for iron removal of potassium feldspar at home and abroad are mainly magnetic separation and flotation. For example, Gejiu potassium feldspar mine in Yunnan uses dry powder magnetic separation. Although it is easy to process, its technological process is old and old, with high processing cost, high energy consumption, low profit, low efficiency, monotonous products, and by-products cannot be comprehensively utilized. When there is a wind, the dust is flying and the air pollution is serious. Potassium feldspar mine in Hubei adopts flotation, and its disadvantages are that chemical substances need to be added, the production cost is high, resource waste is serious, and environmental protection efficiency is poor. Contents of the invention [0003] The ...
