Abstract

The invention relates to the technical field of silica sand, and discloses a silica sand preparation process, which comprises: 1) crushing: crushing cleaned raw ore to obtain a crushed material with aparticle size of less than 10 mm; 2) sand making: adding the crushed material obtained in the step 1) into a sand making machine, carrying out sand making, screening through a 40-70 mesh sieve afterthe sand making, and carrying out mud removing treatment to obtain primary screened sand; 3) wheel grinding: adding the primary screened sand obtained in the step 2) into a wheel grinding machine, grinding, screening through a 8-10 mesh sieve after the grinding, and carrying out mud removing treatment to obtain screened powder sand; and 4) magnetic separation: adding the screened powder sand obtained in the step 3) into a magnetic separator, and carrying out magnetic separation to obtain magnetic separation sand. According to the invention, the preparation process is simple in operation flow,and improves the processing efficiency; and the silica sand prepared by the process is high in purity, centralized in granularity and high in grade, and meets the requirements of users on the physicaland chemical properties of high-purity and high-precision silica sand.

Description

Technical field [0001] The invention relates to the technical field of silica sand, in particular to a process for preparing silica sand. Background technique [0002] Silica sand, also known as quartz sand, is a refractory particle with quartz as the main mineral component and a particle size of 0.020mm-3.350mm. Silica sand is a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO 2 , As an important industrial mineral raw material, it is widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. [0003] The purity of silica sand is different, and the physical and chemical properties are different. High-purity silica sand with higher purity has better physical and chemical properties and is used in many high-precision industries, such as electronics, IT, national defense, etc. With the continuous development of science and technology, t...
