Lecture 4 Mining Waste Sgu
the amount of tailings that remain is controlled by what grade the ore is, meaning the percentage of valuable minerals in the ore. for example, if the grade of an ore is percent copper, percent of the total ore would be deposited as tailings. iron ores generally have higher grades than sulphide or gold ores, often going over per cent or wastes from underground mining is typically 0.1. where concentration or other processing of the ore is done on site, the tailings generated also have to be managed. ores with a low metal con-tent, say, less than 0.4%, generate significant quantities of tailings. In certain mines where ores have high sulfur content, drainage from mine workings
Vale Evaluating Wet Tailings International Mining
vale took the decision to temporarily suspend the disposal of tailings at the laranjeiras dam, part of the brucutu iron ore mine, while assessing the dams geotechnical characteristics, back in december. during the shutdown, the dam will have the level emergency protocol adopted, vale said.If kararas iron ore mine had chosen a wet tailings storage facility, the tailings pond would have been roughly sq.km based on its 30-year mine life, according to flsmidth. the operation is also in the mid-west region of western australia, an area with scarce water reserves, so losing so much water to wet tailings would have been costly to
