The Impact of Geography on Gold Mining Methods. From the icy tundras of Siberia to the sunburned landscapes of the Australian outback, geography sets the stage for the drama of gold extraction. The scattered geography implies …

Special focus was given to the application of cyanide-based gold extraction techniques. Once again, it was concluded that cyanidation is an important technology used for gold leaching in the EU. Whilst alternative reagents have been tested, some of which have developed to commercial scale outside the EU, their adoption have been impeded by a ...

I theorise the process as contradictory-laden and crisis-prone as mineral extraction came to be mediated by the yield requirements, investment motives and risk tolerance of institutional investors. The thesis contributes to key debates on financialisation and mineral extraction within geography, political ecology and the financialisation ...

The ownership and activism of institutional investors in large publicly traded gold mining companies have re-oriented business strategies toward maximising value for shareholders.

Nevertheless, gold accounts for a few parts per billion of the mass of the Earth's crust. While it's not economically feasible to extract much gold, there are about 1 million tons of gold in the top kilometer of the Earth's surface. The abundance of gold in the mantle and core is unknown, but it greatly exceeds the amount in the crust.

2016. In West Africa, large social movements against mining are so far relatively absent from the protest scene. In contrast, a major point in conflict is the competition for gold between artisanal and small-scale miners and large-scale mining companies (e.g. Engels forthcoming, Okoh 2014), in particular in countries with a long tra-dition of artisanal and small-scale mining (ASM) and a …
