Claim:
1. A method of ore processing comprising in any order the steps of: for each ore constituent that has to be separated, assaying the ore for a predetermined temperature range, said assaying comprising: bringing a known volume of the ore constituent to a predetermined original first temperature; adding to or extracting from the known volume of the ore constituent a known amount of heat; measuring an original second temperature immediately after the addition or extraction of the known amount of heat; and repeating these steps by successively starting by bringing the known volume of the ore constituent to a new predetermined first temperature that is a selected fraction of a degree different than the original first temperature; and, during processing, dumping an ore constituent that has to be separated into its bin after ensuring that said ore constituent that has to be separated is divided in volumes equal to the known volume used during the assaying, and that to or from each of said volumes of ore constituent same know amount of heat, as in the assaying, is added or extracted, and after determining that its first measured temperature and its second measured temperature are matching the corresponding temperatures from the assaying.
