Dec 07, 2018 · Gold is a precious metal and also a chemical element with atomic number 79. When not mixed with other metals it is reddish yellow, heavy, soft, easy to work with, and conducts electricity readily. Gold is part of a group of metals called noble metals, which include gold, silver, and platinum; they all resist chemical action, do not corrode, and are not easily changed by acids.
Project Description. –. Osisko Development, through its 100%owned subsidiary Barkerville Gold Mines Ltd., is proposing to construct and operate the Cariboo Gold Project, an underground gold mine and associated infrastructure and activities, in the historic Cariboo Mining District in eastcentral BC, east and southeast of the City of Quesnel.
A first series of tests studied metallurgical recoveries that could be achieved with gravity separation. These tests produced a concentrate grading from 18,158 to 20,968 g/t Au, with recoveries in the order of 50–60% of the gold from the ore. The degree of grinding ranged from 58 to 80% minus 200 mesh; recovery improved as the grind became finer.
Focussing on the gold industry, Gekko replace highenergy whole ore treatment of gold by carboninleach (CIL) methodologies with beneficial lowenergy process solutions.
