Methods for minimizing and eliminating wastes in the production of minerals and metal commodities include [1]: Using cleaner production techniques; Environmental control technologies; Using waste as raw material, and; Reducing the amount of waste produced through process re-engineering.
Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs.

Introduction to Copper Smelting Techniques. Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.
Open-pit mining is the technique used in the Kennecott mine which is digging a pit to extract to minerals. Daniel Jackling was the man that introduced open-pit mining in Utah and is seen as the father of Utah copper mining.

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Copper is not very toxic in comparison to other metals and early humans used too little of it to begin concentrating it in soil, air, or water to the extent that it would affect human health or ecosystems. It appears that during the first few thousand years of its use, humans experiment with and learned techniques to utilize copper.
