Pre-concentration. Recovering mineral-bearing particles into a smaller volume saves energy. Pre-concentration is one step that Gekko Systems applies, and advocates, to design and deliver world-leading energy-efficient flowsheets. Simply put, pre-concentration drastically reduces the ore mass that reports to intensive downstream …

Most elements need to be concentrated into amounts that can be economically mined from ore deposits (usually hundreds to thousands of times their crustal abundance).
Ore deposits are metallic minerals in sufficient volume and concentration to be extracted economically. They are generally formed through one of three geological processes. Magmatic ore deposits are concentrated within a body of igneous rock. Elements that were once widely dispersed in low concentrations in the magma …
Forms of Lead and Zinc Ore The two principal minerals containing lead and zinc are galena and sphalerite. These two minerals are frequently found together along with other sulfide minerals, but one or the other may be predominant. Galena may contain small amounts of impurities including the precious metal silver, usually in the form of a ...
