Malaysia has 112 identified mines listed in The Diggings™. The most commonly listed primary commodities in Malaysia mines are Tin, Aluminum, and Iron .At the time these mines were surveyed, 11 mines in Malaysia were observed to have ore mineralization in an outcrop, shallow pit, or isolated drill hole—known as an occurance mine. 1 Malaysia has 6 prospect mines. 2 82 …
One of the major problems related to blasting operations in open-pit mines is the formation of cracks on the benches behind the last row of blast holes or back breakes. Power Deck blasting has been introduced as a new and alternative method for conventional blasting, which improves blasting results by explosive energy utilization enhancement. In this technique, there is an air …
Geological map of the Mining Complex. 1.2. Filtered Tailings The facilities that filter the tailings from the iron ore Plants inside the mining Complex are capable of filtering and processing approximately 54 million tons of tailings on a dry basis (filtrate) per year. The tailings pulp from the iron ore extraction process passes through cycloning

The geotechnical information collected is stored in two databases, SABLE Warehouse and MineMapper3D before it is imported into the Datamine mining software package. The geotechnical parameters, mining rock mass rating system (MRMR), uniaxial compressive strength (UCS), fracture frequency per metre (FF) and rock quality designation (RQD), are ...
2. Materials and Methods 2.1. Materials. The iron ore tailings to be used in the electroosmosis experiments were obtained from an ore processing waste dam near Sivas province. The iron ore with an average of 56% Fe grade brought from the mine is ground under 2 mm in rod mills and hydrated to 65% Fe concentrate grade and fed to magnetic separators.
and Indonesia. The iron ore tailings data was obtained from seven mines located in Western and South Australia. The nine sets of nickel tailings data were obtained from Western Australian nickel sulphide mines with both 'oxide ore and fresh hard rock ore. In addition, selected data from tantalite mine tailings and aluminum tailings in

Geotechnical analysis plays an important role in determining mining method selection. This study presents the geotechnical design analysis of a potential U/G iron ore Mentes Mine at Yahyali province of Kayseri district in Turkey. Iron ore body is initially planned to be mined by using long hole mining method.
The major motivation for creating an internal tool for geotechnical data analysis originates from the need to standardise geotechnical design process within Pilbara Iron Ore, as envisaged in early 2015 by the overall strategy of the leadership team of planning and technical in BHP Iron Ore. The software would enable
