Mining and Biodiversity Protection – Efforts at International Governance August 22, 2017 Recently, I was asked to contribute a small section on mining and biodiversity to the first global assessment of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.

Feb 07, 2018· Mining refers to the process of extracting metals and minerals from the earth. Gold, silver, diamond, iron, coal, and uranium are just a few of the vast array of metals and minerals that are obtained by this process. Mining activities require the clearing of large areas of land. The chemicals used in the mining process often escape into the environment causing largescale pollution.

The Martabe Gold Mine is located on the boundary of the Batangtoru Forest, an ecosystem recognised for its high biodiversity value. Although the operational footprint of the Martabe Gold Mine is very small compared to the total area of this ecosystem, impacts on biodiversity at the site are recognised by the Company as a significant environment aspect requiring careful management over the life ...

Biodiversity and ecosystem services are intrinsically linked: biodiversity contributes to the processes that underpin ecosystem services; biodiversity can serve as an ecosystem service in and of itself (for example, genetic resources for drug development); and biodiversity constitutes an ecosystem good that is directly valued by humans (for ...
