The first phase of the re-treatment process is to obtain credible information with the sampling programme (and the subsequent metallurgical testwork) a 网页2017年9月7日 Background. Recent major tailings dam failures have led to an industry-wide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly 网页2010年7月3日 16.2.1 Tailings Dams. The design, construction, and operation of tailings dams is a major consideration for most new mining projects, as well as for many existing operations ( Vick, 1984 ). It is economically advantageous to site the impoundment close to the mine, but this imposes limits on site selection. 网页2022年1月31日 solutions based on tailings sand dams and, in consequence, a trend followed to the use of alternative types of containment dams. In the 1970’s, embankment dams of the type used in water reservoirs were adopted.

It is estimated that between 1961 and 2019, 2375 people lost their lives due to a tailings dam failure. In 2019, a catastrophic collapse of the tailings dam at the Córrego do Feijão iron ore mine in Brumadinho, Brazil killed more than 230 people and destroyed large sections of agricultural land. 网页2015年3月25日 JESSIE Mine in Gwanda District is constructing a $1,2 million slimes dam and lining it to prevent the pollution of both underground and surface water by mining effluent.
