在苏联随着油气产量的增加,与钻探有关的工作量也急剧增长,如大量制取在钻探中必须使用的加重剂。目前,生产重晶石加重剂用的是重晶石浮选精矿。实践表明,由于在重晶石精矿中残留有浮选药剂,所以给这种精矿带来一系列很大的缺点。为研制合理的重选工艺,西伯利亚动力钢铁厂对重晶石矿石的物质组分和可选性进行了研究,用的是托尔切因矿床的三个试样、库捷尼-布卢克矿床的三个试样及科尔
With the increase in oil and gas production in the Soviet Union, the amount of work related to drilling has also risen sharply, such as the massive preparation of weighting agents that must be used in drilling. At present, barite flotation concentrates are used in the production of barite weighting agents. Practice shows that due to residual flotation reagents in barite concentrate, so to bring a series of serious drawbacks of this concentrate. In order to develop a reasonable re-selection process, Siberian Power Steel carried out a study of the material composition and selectivity of barite ore using three samples from the Torceine deposit, Three samples of the deposit and Cole
