The sand must be clean, uniformly sized, and of high quality to ensure the integrity of the castings. In the foundry industry, green sand casting is the most common method. Green sand comprises high-quality silica sand, bentonite clay, water, and coal, with each component playing a crucial role in the casting process.
It can be said that all high-quality silica sand is produced by wet beneficiation process. The commonly used purification processes for high-purity quartz sand include washing and classifying, scrubbing, magnetic separation, flotation, acid leaching, and microbial leaching. #1 Washing and Classifying

1. Washing-classifying-desilting: In the quartz sand beneficiation process, the fine-grained grade with a particle size of less than 0.1 mm is usually called slime.For quartz sand with a large amount of clay and ore mud, as the particle size …
For raw silica sand as shown in McLaws (1971), it is classified as high-grade silica sand, based on the component SiO 2 = 99 wt. % (Ibrahim et al., 2013). In Figure 3, the impurities in raw silica ...
(91.5-98.8) was obtained. For raw silica sand as shown in McLaws (1971), it is classified as high-grade silica sand, based on the component SiO 2 = 99 wt. % (Ibrahim et al., 2013). In Figure 3, the impurities in raw silica sand which is associated with siliceous during the geological weathering process of sands can be noted. Shaking table
The iron impurities in silica sand mainly exist in various forms such as muscovite, pyrite and iron oxides. The existence of iron impurities greatly reduces the use value of silica sand and affects the quality of products. Therefore, it is very important to remove iron from silica sand.
