Oct 01, 2021 Mine tailings, especially historical ones, can contain economically feasible resources, and given the right condition, such tailings could be reutilised through a waste valorisation concept. A prominent example are the Witwatersrand gold mine tailings in South Africa, which have been reused in small-scale projects.
Oct 01, 2011 One of the major properties of the PGM industry in South Africa which makes it attractive for the mineral carbonation process is the vast volumes of Ca and Mg-rich tailings produced annually. During the period June 2009 to June 2010, the major players in the PGM industry ( Anglo American plc.
South Africa is a mineral-rich country with metals such as gold, copper, and platinum group metals being exploited to a significant extent in the countrys mining history. Mining generates large volumes of tailings, with consequent disposal and environmental problems. By far the most gold that has been mined in South Africa (98%) has come from

Mar 19, 2018 Types of mine wastelands. There are two types of mining, underground and surface mining (Northey et al. 2013), and the process starts by stripping and/or destroying the vegetation and removing the topsoil and overburden to varying extents (Cooke and Johnson 2002 Gathuru 2011 Mensah 2015).Depending on the quality of the ore, the processing
In this paper, the term tailings is used interchangeably with the broader term mine residue deposits (MRDs), which is used in South Africa to denote dumps, heaps, piles, fillings or tailings dams consisting of mine residue, which usually project above the natural ground surface, but may occupy the space of a pre-existing excavation .

MINERALS COUNCIL SOUTH AFRICA COMMENTS ON THE DRAFT GLOBAL TAILINGS STANDARDS 1. Introduction The Minerals Council South Africa is a mining industry employer organization that facilitate interaction among mining employers to examine policy issues and other matters of mutual concern to formulate desirable industry standpoints.
The tailings dumps were hydraulically mined, reprocessed and stored in an engineered impoundment located 10km south east of Kalgoorlie. From the 60 million tonnes of tailings mined 695,000 ounces of gold was recovered by Carbon-in-Circuit (CIC) and Carbon-in-Pulp (CIP) leach and absorption circuits (Kaltails 1998 Normandy 1998).
The technical and economic feasibility or re-processing hundreds of millions of tons of tailings in a number of historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term
Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africas Witwatersrand gold processing operations. According to Munyar Chirisa, a chemical engineer and senior manager of Deloitte, any tailings dump can be considered a potential mineral asset as long as it contains
mining dumps of which 350 are in the Johannesburg region, covering about 320 000 hectares of surface area. Due to the high cost of primary gold mining in South Africa and the prime real estate occupied by some of these dumps, reprocessing to recover economic value from minerals and has generated much land interest in the last number of years.
