ProcessesAn 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 nonferrous metals from iron ...BACKGROUND OF THE INVENTION. The present invention relates to a process for extracting nonferrous metals from ironbearing scraps containing such metals, in which the scraps are heated in the presence of a copperbearing material and a slagging agent for iron so as to collect in a copper phase at least part of the nonferrous metals contained in the scraps and to slag the major part of the ...
Extraction of Metals from Ores – Different Processes InvolvedThe main aim of designing an extraction process is to minimize the cost and gather the purest form of the metal as much as possible. The conventional metal extraction processes will be discussed elaborately on this concept page. The simpler the process, the better and more costeffective it is for the industries to extract metals from their ores.
Extraction and Refining of the Platinum Metals | Johnson ...The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other, followed by final refining. Operations to achieve this can roughly be divided under three headings:
At this stage of the process, the ...The blister copper produced by this process is 99% pure copper. The name 'blister' copper comes from the fact that this final process produces bubbles of sulphur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining.
