STET Dry Calcium Carbonate Beneficiation / Limestone:
The STET separator has been successfully for the removal of quartz and other acid-insoluble contaminants from finely ground calcium carbonate used as a filler or whitening agent. Acid anaghị edozi (NJ) Ule bu uzo eji eme ka otutu ihe ojoo noo na calcium carbonate. Silicates, dị ka quartz, mica, na talc, tribo-ụgwọ ike na-adịghị mma ikwu na carbonates na nke ọma nkewa e rụzuru na isi mmalite nke calcium carbonate nwalere na pilot-ọnụ ọgụgụ na a ngosipụta osisi. Improvement in product brightness is also achieved for many sources of calcium carbonate beneficiation as the tribo-electrostatic belt separation technology is also effective in removing trace amounts of dark contaminates such as graphite and metal sulfides. Kwa ọnwa pụta n'ihi na a pilot-ọnụ ọgụgụ nọgidere na-arụ ọrụ separator nhazi calcium carbonate gosiri n'okpuru ke okpokoro. Ngosipụta a osisi ji a nọgidere na-arụ ọrụ STET pilot-ọnụ ọgụgụ separator na nkezi ndepụta ọnụego 10 ton kwa hour.
