In-pit crushers feed an extensive conveyor belt system that delivers ore to the concentrators. In 1987, solvent extraction/electrowinning (SX/EW) production of pure cathode copper from dump leaching was started, marking the continuation of the legacy of leaching begun in the 1890’s.

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench production. Since the

The application of mobile in-pit crushing and conveying in large, hard rock open pit mines With the rapid increase of fuel prices in the last two years, there has recently been reconsideration of the application of crushing and conveying in open pit mines. This presentation examines their potential role in hard rock base metal and gold mines.

Todays open pit mines operate in ever-more-remote locations under harsh conditions. They need to manage increasing transport distances. And they face volatile raw material prices and increasing energy costs. In this situation, control over energy performance and equipment condition becomes key. Digital mining can help.

These components, too, originate from vertical conveying and allow for transport of material over inclines of up to 90 degrees. RopeCon can also be extended in line with the axis of the conveyor belt. As the open pit mine grows and changes, the loading or discharge point can be adjusted flexibly along that axis to meet the new requirements.

(a) open pits are getting deeper requiring lower mining cost solutions, and (b) there is increasing pressure on mining companies to reduce carbon emissions. In-pit crushing and conveying (or IPCC) is a potential solution for both issues. And when we say potential, we mean that it will not work for every case.

Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

The vendors indicate the conveying system should be able to achieve heights of 700 metres. This may facilitate the use of internal shafts (winzes) to hoist ore from even greater depths in an expanding underground mine. It may be worth a look at your mine.
