During this review, lithium was recovered from lepidolite by way of iron sulphide (FeS)–CaO roasting and water leaching. The thermodynamics happening through the roasting of lepidolite and also the additives was simulated by utilizing the HSC programme. The simulation suggests that SO2/SO3 formed in the oxidation of FeS performs an https://edmundp912sgh4.wikigop.com/user
