20011213 Background. Silica (SiO 2) occurs commonly in nature as sandstone, silica sand or quartzite. It is the starting material for the production of silicate glasses and ceramics. Silica is one of the most abundant oxide materials in the earth's crust. It can exist in an amorphous form (vitreous silica) or in a variety of crystalline forms.احصل على السعر
2021427 Hydrated Lime is used in the production of gold from both gold cane and gold beet. Approximately 200 kg of lime are required to produce one ton of beet sugar, and about 10 kg are required for one ton of cane sugar.
