Copper processing Roasting, smelting, and converting

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

Extraction of Metals Methods of Extraction of Metals

Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.

Processes extraction, mining, smelting, refining

An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting This is where the chemical reactions start.

Process for extracting non-ferrous metals from iron

BACKGROUND OF THE INVENTION. The present invention relates to a process for extracting non-ferrous metals from iron-bearing scraps containing such metals, in which the scraps are heated in the presence of a copper-bearing material and a slagging agent for iron so as to collect in a copper phase at least part of the non-ferrous metals contained in the scraps and to slag the major part of the
