US5181956A - Method for purifying TiO2 ore - Google Patents

Process for beneficiating titanium bearing ore selected from the group consisting essentially of titaniferous ores, leucoxene, rutile, perovskite, and sphene comprising: (a) contacting said ore with an aqueous solution of a mineral acid having a concentration of about 3-30 percent by weight said contacting taking place at a temperature of about 160°-300° C., until the desired amount of impurities are solubilized and a leachate is formed, (b) removing the leachate from the product of step (a).

copper extraction and purification - chemguide

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main process streams; one for sulfide ores and the other for ore that is being weathered to oxidize sulfides the so-called oxide ores.

Metallurgic Processes | Boundless Chemistry

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores ( leaching ).
