Problems solved by technology

[0002] High-grade high-quality quartz sand is the main raw material for glass production, especially the quartz sand for making white glass requires high silicon content and extremely low iron content. High iron content will cause white glass to turn blue and foam, which will affect the quality of glass, while raw ore Most of the ore with high iron content is concentrated in the fine-grained sand with a particle size of less than 100-130 mesh. The traditional process is to make the raw ore after primary selection into sand after screening, desliming, scrubbing, and grading. The screening process usually uses a layer of The fine-grained sand below 100-130 mesh cannot be removed by the sieve once, so the iron content of the sand remains high, which affects the quality of white glass
For this reason, people have improved on the basis of the traditional technology. After the rough selection of the raw ore, after screening, desliming, and multiple scrubbing, electronic iron removal is added to remove iron impurities, thereby improving the sand grade and making it meet the requirements of white glass. Production requirements, but the above-mentioned process has disadvantages such as large investment, high cost, and inconvenient maintenance

Embodiment 1

[0008] The silicon content of the mined quartz sand raw ore is less than 92%, the iron content is between 0.2-0.25%, contains a lot of impurities, and the particle size varies greatly.

[0009] After primary selection of quartz sand raw ore, it goes through the following process steps:

[0010] 1. Under the action of water flow, the raw ore flows into the vertical screen through the channel for screening. The screen is divided into two layers. The upper screen is 20 mesh, and the lower screen is 130 mesh. The particle size is greater than 20 mesh and smaller than The 130-mesh coarse-grained sand and fine-grained sand are all filtered out, and the ore with a particle size between 20-mesh and 130-mesh is retained to enter the channel;

[0011] 2. The screened ore flows into the deslimer through the channel for desliming, and the mixed mud and sand in the ore are removed;

[0012] 3. The deslimed ore flows into the scrubbing machine through the channel for scrubbing to further r...

Abstract

The present invention discloses a mineral concentration process for quartz sand, and is characterized by that the green ore is undergone the processes of primary separation, screening at twice by using more than two layers of sieve screens, desliming, washing and sorting so as to obtain finished product quartz sand with high quality.

Description

technical field [0001] The invention relates to a quartz sand beneficiation process, in particular to a quartz sand beneficiation process using multi-layer screens for screening. Background technique [0002] High-grade high-quality quartz sand is the main raw material for glass production, especially the quartz sand for making white glass requires high silicon content and extremely low iron content. High iron content will cause white glass to turn blue and foam, which will affect the quality of glass, while raw ore Most of the ore with high iron content is concentrated in the fine-grained sand with a particle size of less than 100-130 mesh. The traditional process is to make the raw ore after primary selection into sand after screening, desliming, scrubbing, and grading. The screening process usually uses a layer of One-time screening by the screen cannot remove the fine-grained sand below 100-130 mesh, which makes the iron content of the sand r...
