Using scraps, which are secondary sources, instead of ores in the production of gold is technologically easier, more economical in terms of energy and material requirements and environmentally cleaner.

Especially the recovery of gold is more environmental friendly compared to production from ore. Also in the recovery of gold, a large part of the cost is for the operations performed on the stage of making the wastes, which arise in the process, harmless to the environment.

In particular, the recovery of gold from the ore is more environmentally friendly than production. Also in the recovery of gold, a large part of the cost of production of wastes that arise in the process, making it harmless to the environment consists of the operations performed on stage.
