The result show similar depletion of silica from the unaltered distal samples through the altered proximal samples, which is also believed to be the result of leaching as in the Liji mineralization area. However, the silica content of 11.80 wt% in the baryte separate is high reflecting silica contamination in the separate.

the cooling stage the silica forms discrete silica colloids which are aged and filtered out using a continuous ultrafiltration (UF) circuit to concentrate the silica from its incoming concentration to a 4wt% solution. Filtrate from the process is now low in silica and able to be used for further mineral extraction.

Barite Occurrence. Barite often occurs as concretions and void-filling crystals in sediments and sedimentary rocks.It is especially common as concretions and vein fillings in limestone and dolostone.Where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes found at the soil-bedrock contact.

The silica removal proved to be effective when the temperature was from 70– 90EC and the settle time was over 1.0 h. When the magnesium salt was combined with pH regulation and zinc coagulation, the silica could be removed from heavy oil wastewater to reach the standard of less than 50 mg/L.
