Recovery of copper from smelting slag by sulphation roasting and water leaching 411 Materials and experimental methods Experiments were conducted using a reverberatory furnace slag from the Bor Copper Concentrator, Serbia. The slag was sampled from the crushing line before entering the milling section of the concentrator.
of slag/pyrite/copper concentrate and the effect of the added iron powder to leaching on the metals dissolution were investigated. Under optimum conditions, 99.6% of copper and 98.4% of cobalt were extracted in roasting at high temperatures in a closed medium 3:6:6 of slag/pyrite/copper concentrate rate then roasting at 600 °C at 5 hours.
Buying copper ore, copper concentrate, copper slag, copper sludge. JHM need to buy copper raw materials, such as copper ore, copper concentrate, copper slag, copper sludge and so on. Our required copper materials ahould contain more than 5% Cu. If you could supply any of above mentioned materials, please don't hesitate to contact me.
Copper slag is a by-product of copper extraction by smelting. During smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below. Characteristics. Slag from ores that are mechanically concentrated before smelting contain ...
