Contaminant Removal Process: Froth Floatation process can be followed for removing mineral contaminants in acidic conditions. In froth floatation process a cationic collector is used for removing mineral contaminants like feldspar and anionic collectors for removing mineral contaminants like iron or iron coated grains.
Classification: After removal […]

Following are the steps followed in processing silica sand for making it usable for glass industrial application.

Preliminary Screening: The raw mined sand is first taken through an initial screening for removing
trash materials. Vibrating Screen is the most commonly used equipment for this operation.
Washing Process: After preliminary screening, […]
