Colourimetric determination of copper ore. In association with Nuffield Foundation. No comments. An ore is any rock from which a metal may be extracted. To decide whether an ore is worth mining it is necessary to find out how much of the useful mineral it contains. This experiment illustrates an example of how this might be done. Class practical. An ore is any rock from which a metal may be ...

WhatsAppعرض المزيدOre is the rock from which an element ultimately will be extracted. The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating mines—much less than 1% by weight for gold, more than 60% by weight for some ironore mines. Ore usually is transformed into concentrate at the mine site. Concentrate is an upgraded material. For ...
