INFLUENCE OF HEAT TREATMENT PARAMETERS OF SERPENTINITE ON ITS PROCESSABILITY INTO MAGNESIUM-CONTAINING MATERIALS

Serpentinite is a promising and economically accessible raw material for producing magnesium oxides and salts, which are widely used in various sectors of the chemical industry. Currently, a significant number of technologies have been developed for processing serpentinite raw materials. Despite differences in the process flowsheets, most of them are based on two key processes: acid leaching (using sulfuric, hydrochloric, and nitric acids) and thermal activation (sintering) [1–5].蛇纹石（Serpentinite）是一种极具应用前景且经济易得的原料，可用于制备氧化镁及镁盐，而这类产品广泛应用于化工行业的多个领域。 目前，针对蛇纹石原料的加工技术已得到大量开发。尽管各技术的工艺流程存在差异，但绝大多数均基于两大核心工艺：酸浸法（使用硫酸、盐酸及硝酸）与热活化（烧结）工艺[1–5]。
