In most of the cases, the cheapest way to improve the fragmentation of the ore is by changing the drillingandblasting design parameters. It of course increases the mining costs, but at the same time decreases the costs of the following processes, which

Agglomeration processes are necessary to utilize the iron ore fines (10 mm) that are generated due to mechanized mining of iron ore. Sintering is one of the most prevalent agglomeration processes due to its lower capital cost and operational flexibility. Sintering combines iron ore fines in the size range .1510 mm along with fluxes ...

In this study, a sintering test of highalumina limonite from Indonesia, matched with an appropriate magnetite concentration, is performed. The sintering yield and quality index are effectively improved by optimizing the ore matching and regulating the basicity. For the optimal coke dosage of % and basicity of, the tumbling index of the ore blend is found to be % and the ...

This paper studies the production and distribution planning problem faced by the iron ore mining companies, which aims to minimize the total costs for the whole production and distribution system of the iron ore concentrate. The ores are first mined from multiple ore locations, and then sent to the corresponding dressing plant to produce ore concentrate, which will be sent to distribution ...

These can include increased plant throughput, improved product quality, maximized production of lumps in iron processing, or reduced fines in the final product for coal operations. High energy consumption is one of the biggest concerns in most operations, thus, in most optimization processes, the goal of reduced energy consumption is often a ...

Ore blending is an essential part of daily work in the concentrator. Qualified ore dressing products can make the ore dressing more smoothly. The existing ore blending modeling usually only considers the quality of ore blending products and ignores the effect of ore blending on ore dressing. This research proposes an ore blending modeling method based on the quality of the beneficiation ...

Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the orebearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it's usually necessary to sink vertical mine shafts to access coal which is deposited in layers or 'seams ...

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