The types of calcium carbonate particles are based on their morphology. Calcium carbonate particles (CCPs) are white color powder, insoluble in water but soluble in HCl, biocompatible, pH sensitive, The solidification of copper mine tailings was investigated by using the natural biological process known as microbial induced calcium carbonate precipitation (MICP) as a potential method to valorize this waste stream. A submergent method was used to grow bio-columns and the toxicity of copper on Sporosarcina pasteurii (the ureolytic Copper mine tailings valorization using microbial induced calcium

Acid mine drainage: Prevention, treatment options, and
2. Methods. This review is devoted to provide up-to-date prevention of AMD generation and treatment options. A literature search in the Scopus database for “acid mine drainage” and “acid mine” in the keywords from 1980 to 30 August 2016 resulted in a total of 4303 and 5590 articles, respectively.Introduction. Acid mine drainage (AMD) is acidic effluent from operating and abandoned mines, and often includes toxic elements. AMD can be neutralized by limestone (CaCO 3) or calcium hydroxide (Ca(OH) 2), and toxic elements are removed as hydroxides or other chemical forms to avoid environmental impacts.However, the cost of Comparative study of acid mine drainage neutralization by calcium

Applied Sciences Free Full-Text The Processing of Calcium
Every year a million tonnes of calcium rich agro and industrial waste are generated around the whole globe. These calcium rich waste like finger citron, shells of cockle, mussel, oysters etc., and egg shell are biological sources which have various organic compounds. The inorganic calcium rich waste includes gypsum, dolomite, sludge etc., To promote the utilization of high-calcium and high-alkali calcium carbide slag (CCS) in the construction industry, a pre-carbonation method has been employed to convert Ca(OH) 2 in CCS to CaCO 3 to improve the compatibility of CCS with cement. The study investigated the effects of different carbonation durations (10 min, 20 min, and 30 Comprehensive performance study of aluminum ash and calcium
