The Injection of "Slime" Slurry for Treatment of Dissolution Problems at the Foundation Rocks of the Site of the State Company for Phosphate Plants, Al-Qaim, Western Iraq
Abstract
Sulfuric acid pollution still represents constructional problems at the basement rocks of the State Company for Phosphate. According to the concepts of the geochemical engineering, such problem can be treated by slime slurry injection (ssi). The data of laboratory experiments show that the ssi leads to: 1. induced gypsum cementation reaction in carbonate basement rock and make them less porous i.e. increase its compressive strength and 2. fill in dissolution cavities and channels with gypsum crystals which decrease the rate of migration of underground water to adjacent constructions of the manufacture of sulfuric acid production. The present study suggest few additions to increase the efficiency of achievement of ssi goals.
