Washed sand is construction sand that is obtained after the natural silica sand is washed by a silica sand washing plant and meets the construction standards of various places both artificial sand and natural sand contain certain impurities if such sand is used for the construction of the project it will result in a strong degree of ...
Quartz sand xenoclasts contain hematite, limonite, biotite and other weak magnetic separation minerals as well as secondary cast iron in the crushing process. Usually, strong magnetic separation equipment is used to remove these impurities. If there is magnetite impurity in quartz sand, it can be removed by weak magnetic separation equipment.
The invention relates to a physical impurity removal process for quartz sand. The process takes full consideration of the difference in physical and chemical properties between quartz minerals and coexisting impurity minerals, avoids the process unfavorable for the production of highpurity quartz sand in the impurity analysis process of quartz ores, and adopts a purephysical method to ...
Quartz sand of Mojosari deposit from Rembang, Central Java has been beneficiated using oxalic acid to enhance its purity, especially that is associated with the removal of iron oxide impurities. The removal of metallic impurities has been studied under experimental conditions to optimize the process parameters such as oxalate
