水中和土壤中的微机体对各种自然过程的影响早就知道,并且是许多科学研究的对象。居显著地位的是对于在各种细菌影响下金属和矿石所经受的各种变化的研究。这些研究为从某些矿石和金属产品回收金属方法开辟了远景。关于这点,在回收铁、锰、铀、金,特别是铜方面所获得的结果得到了证实,在铜的方面,这个方法在工业实践中得到了应用。。罗马尼亚有色金属矿床个别贫矿区的地质 The effects of micro-organisms in water and soil on a variety of natural processes have long been known and are the subject of many scientific studies. Habitually prominent is the study of the various changes experienced by metals and ores under the influence of various bacteria. These studies open the way for the recovery of metals from certain ores and metal products. In this connection, the results obtained in the recovery of iron, manganese, uranium, gold, in particular copper, have been confirmed, and in the case of copper this method has been applied in industrial practice. .
