An Investigation into the Leaching of Enargite Under Atmospheric Conditions
The leaching behaviour of enargite was studied under atmospheric pressure. The kinetics of enargite dissolution appear to be extremely slow under the conditions studied using both small scale shake flasks and bench scale ...
Test of an Innovative Stochastic Design System on an Open Pit
Commodity markets are fundamentally cyclical, exposing mining companies to large swings in profitability during periods of economic boom and bust. Although this is well documented, companies continue to produce mine plans ...
An Experimental Investigation of the Effect of Blasting on the Impact Breakage of Rocks
Size reduction represents one of the most energy-intensive and costly processes in the extraction of valuable minerals and rocks. Drilling and blasting, being the first operation in the size reduction chain, may have a ...
Associated Sulfide Minerals in Thiosulfate Leaching of Gold: Problems and Solutions
The effects of some associated minerals on thiosulfate gold leaching were studied through thermodynamic analysis and leaching experiments on composite ore samples containing various minerals and a reference silicate gold ...
Comparison of Microwave Drying and Conventional Drying of Coal
The moisture contents of the final coal products from processing plants are often too high and do not meet the requirements of the client. In many cases, drying becomes a necessary step to control the moisture content. ...
THE INFLUENCE OF VENTILATION MODELING ON PRODUCTION PLANNING
Abstract The main objective of a ventilation system is to provide the quality and quantity of the airflows throughout the mine and to ensure safe and health conditions for the workers to the level specified by the mining ...
