Abstract:
1. A method of ore processing comprising in any order the steps of: assaying the ore to determine what ore constituent has to be separated; heating or cooling a metal object using controlled means for adding or extracting heat, for the purpose of determining the amount of heat added or extracted by said controlled means for adding or extracting heat; determining the expected temperature change of the ore constituent that has to be separated if the same amount of heat is added to or extracted from it; measuring a first temperature of a substantially precise volume of the ore; changing the first temperature of the substantially precise volume of the ore, immediately after the measuring of the first temperature, by exposing the substantially precise volume of the ore to the same controlled means for adding or extracting heat, such that the same amount of heat is added to or extracted from the substantially precise volume of the ore; measuring a second temperature of the substantially precise volume of the ore immediately after the controlled means for adding or extracting heat have been disengaged and determining the resulting measured temperature change of the substantially precise volume of ore; and, determining that the substantially precise volume of the ore in the cup consists substantially of the ore constituent that has to be separated if the measured temperature change is the same as the expected temperature change.
