随着采矿技术的改进和加强有价矿物的綜合利用,在有色金属各矿山,硫化鉄的产量日益增加。但此項产品,目前除供制硫酸外,其他工业用量很少,造成了大量的积压。其次,我国目前尚未发現天然硫化矿床,硫磺的生产多是取自含煤硫鉄矿。其产量虽历年有所增加,但因橡膠、造紙、制藥工业,以及其他化学工业的迅速发展,仍然不能滿足需要。因此,利用浮选硫鉄矿提煉硫磺,在当前来說,实有其重要意义。
With the improvement of mining technology and the enhancement of the comprehensive utilization of valuable minerals, the output of sulfide 日 has been increasing at all non-ferrous metal mines. However, this product, at present except for the preparation of sulfuric acid, other industrial use is very small, resulting in a large backlog. Secondly, the natural sulphide ore deposits have not been found in our country at present, and the production of sulfur is mostly taken from coal containing sulfur ores. Although its output has been increasing over the years, the rapid development of rubber, paper making, pharmaceutical industry and other chemical industries still can not meet the needs. Therefore, the use of flotation pyrite sulfur extraction of sulfur, for the moment, it is of great significance.
