Investigation of old waste dump composition of lean gold-bearing ores from the Golden Pride Project (GPP) mining operation in Nzega district, Tanzania. The search for alternative sources of useful minerals is a pressing issue. ... The paper proposes potential methods for processing lean dumps of gold-bearing ores. One such methods involves ...

In this article, we investigate the possibility of reprocessing gold bearing gold dumps for gold as a sustainable way of reviving the mining sector in Zimbabwe. Heap or vat leaching is a...

In terms of the Mineral and Petroleum Resources Development Act (Act 28 of 2002 as amended), the Minister must grant a prospecting or mining right if among others the mining "will not result in unacceptable pollution, ecological degradation or damage to the environment".

•Processing, shipping and removing legacy dump material has in some cases resolved issues with historic mine dumps •Example is the "Hard Cash" project which had a dump eroding into …

During the gold mining, underground tunnels were created to extract ore and crushed rock waste, with gold processing residues being deposited at ground level, which led to the formation of substantial mine dumps and tailing dams in Johannesburg.

Extraction of valuable metals from tailings dumps (or residues or low grade stockpiles) traditionally regarded as waste, has long been researched by metallurgists. A number of developments in mineral processing technology …

This article describes the investigation of three distinct mine tailings, and discusses the opportunity of re-processing such secondary mining resources, as part of the overall mining site management.

From the commencement of gold mining on the Witwatersrand in 1887 up to 1984, a total of approximately 4,2 billion tons of gold ore has been milled in South Africa. The deposition of …

The chapter suggests a complete classification of mine dumps based on their genesis; determines their multifactor environmental impact; and gives a methodological …

Whilst aimed at providing a generic overview of the subject, it is strongly influenced by the authors' experience in the processing of sand and slimes dumps at the AngloGold …

The chapter suggests a complete classification of mine dumps based on their genesis; determines their multifactor environmental impact; and gives a methodological approach to ecological and economic risk assessment of the mine dumps affecting the environment.

Whilst aimed at providing a generic overview of the subject, it is strongly influenced by the authors' experience in the processing of sand and slimes dumps at the AngloGold Ashanti Ergo operation in South Africa.

From the commencement of gold mining on the Witwatersrand in 1887 up to 1984, a total of approximately 4,2 billion tons of gold ore has been milled in South Africa. The deposition of gold mine residues has left the country, particularly Johannesburg and its neighbouring cities in the central Witwater­

Extraction of valuable metals from tailings dumps (or residues or low grade stockpiles) traditionally regarded as waste, has long been researched by metallurgists. A number of developments in mineral processing technology have combined to make the retreatment of numerous tailings dumps a profitable
