LITERATURE REVIEW 2.1 INTRODUCTION The objective of this chapter is to present a literature review of tailings dam design and construction in general, as well as a critical review of the engineering properties of gold tailings. A brief history of the South African gold
This review is essentially an overview of the pretreatment processes for the refractory gold ores available in the recent literature. When gold is finely disseminated in sulphides, arsenosulphides, tellurides, carbonaceous and clayey materials direct alkaline cyanidation is not effective for gold extraction.
Literature Background Ecotourism is a relatively new concept, and it is still often misunderstood or misused. Some people have abused the term to attract conservation conscious travellers to what, in reality, are simply nature tourism programs which may cause negative environmental and social impacts.
This appendix is meant to provide a brief review of the literature with regard to environmental and social impacts from mining, as well as key regulatory issues. Key Environmental and Social Impacts Environmental and social impacts of mining have been well documented and
a refractory ore before leaching to achieve better gold extraction. Pretreatment methods are for example chemical blanking, roasting, chlorination, bio oxidation, pressure oxidation, chemical oxidation and ultrafine grinding (Nanthakumar et al., 2007; Celep et al., 2011). If gold ore contains pyrite, the pyrite should be oxidized before leaching.
