Sulfating roasting . Sulfating roasting oxidizes certain sulfide ores to sulfates in a controlled supply of air to enable leaching of the sulfate for further processing. [citation needed] Magnetic roasting . Magnetic roasting involves controlled roasting of the ore to convert it into a magnetic form, thus enabling easy separation and processing in subsequent steps.

A hydrometallurgical process for the recovery of silver, selenium and tellurium from the anode slime produced in the electrolytic refining of copper or lead or from other raw materials bearing these metals, wherein the raw material and concentrated sulfuric acid or oleum are heated at approx. 160°300° C, preferably 160°200° C, in order to sulfate the nickel and the possible copper.

Sodalime roasting was carried out on red mud under reductive atmosphere prior to leaching for recovery of valuable elements such as Al and Na from the red mud. Changes occurring in the mineral phases and the recovery of Al and Na were investigated under different conditions.
