Feldspar Ore Crushing. Feldspar ore is generally quarried from an open pit deposit and transported to the mill by truck. The flowsheet shows a conventional two stage open circuit crushing system capable of reducing the ore to 190; which is suitable for further reduction by rod milling.
Conventional mining in open pit and underground mines involves removing ore (and waste) from the ground, and then processing it to extract the metals of interest. In situ recovery (ISR), also known as in situ leaching (ISL), use solu tions that are pumped through the mineralized body in situ (under ground) to recover metals by leaching.

Apr 01, 20180183;32;Part of an interactive on line booklet about copper mining explaining the early, open pit, 90% of ore is mined by this method. it can be used on ores with as little as 0.1% copper for this reason, leaching extraction is growing in importance. The ore is a mixture of minerals and rock (called gangue). Other properties
Spodumene is usually recovered through conventional open pit mining methods and beneficiated via gravity techniques where the ore is concentrated from 1 2% Li2O to a grade of ~6% Li2O.
Gol e Gohar iron ore mine is located some 55 km southwest of Sirjan in Kerman province. This area is a combination of metamorphic (Paleozoic) and sedimentary (Mesozoic) rocks, consisting mostly of gneiss, mica schist, amphibolite, quartz schist and calcite types of rocks. The operation in this mine is also an open pit facility.
Conventional open pit mining is proposed for the delivery of 100 000 t/month or 1.2 Mtpa of RoM material to the communition and processing facilities. In order to develop the pit design for the Arcadia deposit, an optimised pit shell was first prepared using Dassault System Surpac169; software.
