CBG Bauxite (Aluminium Ore) Mining Operations Mining

Open pit mining. While Sangarédi was the orebody on which CBG’s operations were founded, today between 85% and 90% of its output of raw bauxite comes from the Bidikoum and Silidara pits. After stripping any thin overburden, the ore is blasted and then loaded using hydraulic excavators into haul trucks for transport to the mine stockpiles. Bench heights of up to 8m allow most of the ore to

Mining and Refining Process

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of

Master thesis unileoben.ac.at

thesis was to develop various concepts for mining of the bauxite deposit in an open pit and to compare the possible concepts with respect to their technical and economical advantages and disadvantages. The basis for the work was the data available about the deposit geometry and the bauxite resources. The available data is rough but sufficient in terms of developing a first open pit mining

Mining Glossary, Open-pit Mining, Open-pit Mines, Bauxite

Open-Cut (Pit) Mining A form of operation designed to extract minerals that lie near the surface. Waste, or overburden, is first removed, and the mineral is broken and loaded, as in a stone quarry. Important chiefly in the mining of ores of iron and copper. The mining of metalliferous ores by surface-mining methods is commonly designated as "open-pit mining" as distinguished from the "strip

Surface Mining Methods and Equipment

Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.

Comparison of geostatistical calculations with the results

Geostatistical calculations were carried out on two completely exhausted open-pit bauxite mines in the Iharkut bauxite district, Hungary. Fictitious regular drilling grids were laid on the maps, and horizontal variograms were calculated for drilling grids evaluating the bauxite surface, footwall surface, and bauxite thickness. Point kriging was carried out for all three parameters. Bauxite
