high purity white quartz silica sand 99.99% for glass production price

1. Silica/Quartz Sand is processed from the high quality silica stone, through the process of coarse crushing, roasting, fine crushing, acid treatment, water washing, drying and sieving etc. Specifications: SiO2: 99.2% Pb: 6 ppm As : 2 ppm Cr: 23 ppm

Natural quartz sand are classified into shore sand and sand mountain.Quartz sand is mostly with impurity or mixtures, so generally it should treat differently when handling various mines .According to the content and particle size composition of Fe2O3, Al2O3, Cr2o3, of Tio2, grades are defined. silica and quartz sand can also make quartz sand after the crushing process, they are the main raw materials of glass industry. 2 Applications: We can provide 8-12mesh, 12-20mesh, 20-40mesh, 40-80mesh, 80-100mesh, 100-120mesh ,200 mesh and 325mesh silica/quartz sand granule and powder. It can be used in construction cement/concrete , sand playing/painting/decoration, manufacturing & ceramic industry . 3.Adventages：

1) High quality and purity with low iron content, high electrical resistivity

2) Low hardness & Crossion-resistant

3) Acid-resistant, alkli-resistant, anti-corrosive, anti- acid and anti –alkali
