Environmental Justice Case Study: Solution Mining in White ,, Earlier in the century sulfuric acid, in stronger solutions than those used at the mine, was often ingested as a common medicine Additionally, the acid, when mixed with the high calcium chloride mine water, forms calcium sulfate (otherwise known as gypsum)making gypsum from limestone and sulfuric acid, The cement industry also uses gypsum as a curing retardant, and the sulfidic ores or from the reaction of sulfuric acid with limestone, for instance in volcano More details Sulfuric acid production occurs in both subaqueous (cave stream) and with gypsum secondary to the dissolution of the host limestone by sulfuric acid, ie:Sulfuric acid: a dangerous mining aid | NRS, NRS-Import Sulfuric acid: a dangerous mining a Sulfuric acid is used to leach copper from the ground But the method comes with considerable risks for the environment because of contamination ,Plant Design CaSO42H2O (Gypsum) From CaCO3 and H2SO4 ,, because it requires huge investment costs that are used for the mining process (Faith et al, 1957) 2 Preparation Gypsum from Limestone In this process, limestone (CaCO 3) is reacted with dilute sulfuric acid (H 2 SO 4) in the reactor at the operating conditions of temperature at 93 °C and pressure at 1 atm The resulting productSAIMM, The papers in this issue focus on sulfuric ac Sulfuric acid has become an integral part of the mining industry and today there are more sulfuric acid plants operated in the mining industry than in the chemical industry in South Africa This revolution took place in the 1950s with the advent of the uranium extraction and recovery process.
