Catalytic leaching of ilmenite using hydrochloric acid. The iron content present in the ilmenite is removed by leaching the ore with hydrochloric acid. the enriched tio 2 mineral thus obtained is called synthetic rutile sr or beneficiated ilmenite bi. the quality of the synthetic rutile in terms of tio 2 content mainly depends on the condition of leaching process. the present study envisages

Iron oxide in samples of clay containing % iron oxide was leached in aqueous oxalic acid and hydrochloric acid solutions. Leaching experiments were conducted in the temperature range of 40–80°C for times up to 90 minutes in M to 2 M acid solutions. The mixed kinetic mechanism seemed to be the most appropriate model to fit the kinetic data of leaching in oxalic acid while product

Mining is the extraction[removal]of minerals and metals from the earth. The Nigerian Coal Corporation (NCC) is a parastatal corporation that was formed in 1950 and held a monopoly on the mining, processing, and sales of coal, lignite, and coke products until 1999.. Coal was first discovered in Enugu in 1909 at the Udi Ridge in Enugu,This was found by a British mine Engineer known as Albert Kitson.
