· The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account

· The sodium lignosulfonate has pH value of 6.6, which is slightly acidic, and the expansive soil has pH 7.3. When the additive percentage is increased in the soil mix from zero to 12%, the pH value decreases from 7.3 to 6.9. The soil pH is not altered much when the soil is treated with lignin-based organic polymer.

· Baryte (BaSO4) is a critical raw material with no functional recycling since the used applications are dissipative. Significant quantities of baryte end up in tailings as a side stream from the mining industry. Baryte from a secondary raw material source was used as a filler in plastics for low duty radiation shielding and as an aggregate in radiation
