Stripping Ratio in Open-Pit Mining, Types of SpringerLink

Stripping ratio is the ratio of the volume of waste rock stripped off to the volume of ore exploited during the process of surface mining. It indicates the volume of waste rock required to be stripped for mining per cubic ore. Stripping ratio (see Fig. 1) is an important technical-economic indicator in open-pit mining, which reflects thePlants were grown in an ore body with a gold grade of 1.75 g/ton gold and treated with 0.1 g/kg and 1 g/kg cyanide as aqueous NaCN.

Review of improving the water management for the informal gold mining

ABSTRACT. Colombia is one of the largest producers of gold in Latin America and it has recently increased its production, especially in the Departments of Antioquia, Chocó, Bolívar and Córdoba, which in 2014 produced 90% of Colombia's gold. Most of this production comes from artisanal and Small-Scale Gold Mining (ASGM).Environmental Research Letters, Volume 12, Number 9 Citation Gregory P Asner and Raul Tupayachi 2016 Environ. Res.
