这个实验是利用自然界分布极广的氧化硫杆菌和硫酸盐还原菌,在其繁殖过程中,产生一种强氧化环境和还原环境,使硫化物发生氧化溶解与还原再沉淀的条件,以研究层控硫化矿床含矿溶液迁移和富集作用.氧化硫杆菌的繁殖形成一个强氧化环境,很快地使硫化物氧化为溶解度很大的硫酸盐,因而易于迁移;硫酸盐还原菌的生长可产生一个强还原环境,使可溶性的硫酸盐还原成为难溶的硫化物而堆积成矿.这个实验对研究非岩浆热液型金属硫化矿床,如同生沉积硫化矿床,硫化矿床氧化带以及石膏层地区硫化矿床的形成,具有重要的意义.
This experiment is the use of sulfur dioxide bacteria and sulfate-reducing bacteria are widely distributed in nature, in its breeding process, resulting in a strong oxidizing environment and reduction of the environment, the sulfide oxidation and dissolution and reduction and re-precipitation conditions to study the layer Migration and enrichment of ore-bearing solutions in controlled sulphide ore deposits. The propagation of Thiobacillus thiooxidans forms a strong oxidizing environment that rapidly oxidises sulphides to sulphates of high solubility and thus tends to migrate; the growth of sulphate-reducing bacteria can produce A strong reduction environment, the soluble sulfate reduction into insoluble sulfide and accumulation of mineralization.This experiment on the study of non-magmatic hydrothermal metal sulfide deposits, such as sedimentary sulfide deposits, sulphide ore oxidation zone and gypsum layer vulcanization The formation of the deposit is of great significance.
