过去别洛乌索夫选矿厂处理深槽矿石时把重晶石同废弃物一起抛入了尾矿场。但是石油和化学工业的发展、对钻探泥浆的重晶石加重剂及其他部门原料需要的增加,都要求采取措施回收重晶石。 In the past, Belo Horizonte beneficiated ore was thrown into the tailings along with waste while processing deep trenches. However, the development of the oil and chemical industry, the increasing demand for barite weighting agents for drilling mud and other sectors of raw materials, require measures to recover barite.
