Typically, a Small Scale oxide copper deposit will contain a minimum of 100 million pounds of copper. This will be mined at a rate of about 30 million pounds per year and a production cost of less than $USD 0.50 per pound. Using contract mining to reduce capital costs, the total start up capital cost of such a project is around $15-20 million.

Copper Mining and Processing: Everything you Need to Know

2017/08/04· The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.

SMALL SCALE GOLD MINING AND MARKETING IN

The small scale artisan miners in many developing countries employ very basic tools and equipment to conduct mining operations. In PNG, small operations consist of less capital intensive manual excavations of alluvial gold deposits found in streams/rivers, puddles and ancient river terraces. Panning dish, pick and shovel are the main tools used.
