Copper is mainly absorbed through the gastrointestinal tract, but it can also be inhalated and absorbed dermally. It passes through the basolateral membrane, possibly via regulatory copper transporters, and is transported to the liver and kidney bound to serum albumin. The liver is the critical organ for copper homoeostasis. In the liver and other tissues, copper is …

The deposit contains copper, iron, lead, zinc sulfides along with gold. Their concentrator has flexibility to produce gold doré (a semi-pure concentrate of gold and silver) and separate copper, lead, and zinc concentrates depending on the stockpile blending. In this study, the chosen processing route was to produce a copper concentrate.
