    I am from KL, Malaysia
    Our company wish to set up a sand purification factory in Malaysia
    Our composition report of raw sand varies from 98% to 99% silica
    We wish to produce silica with content of it range from 99.5% to 99.9%

    Please contact me for further work

    Thank you

    1. Shreebalaji says:

      Sir , normal silica sand from River bed and Sea shore silica % will be 95 – 97 % only
      If you require silica 99.5 – 99.9 % you should Crush Quartz Lumps and process it
      OR Fuse the low grade Quarts for high purity
