Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2-, Cu(CN)3=, and Cu(CN)4=-, although Cu(CN)3= is considered the most probable of these. According to leach scientists, the complex having an empirical formula KCu(CN)2, is not a solvent for gold and silver.
Their production capacity amounts to 540 thousand tonnes of electrolytic copper and 1200 tonnes of silver a year. These values place KGHM's smelting potential among the largest producers in the world. The production in the KGHM smelters mainly relies on the company's own resources and copper ore concentrates produced on-site. KGHM's processing
The player cannot fill the ore box while carrying more than one of them in their inventory. Attempting to fill the ore box whilst carrying several of them simply results in the player character exclaiming "I can't hold all these ore boxes!", with no ore being added to the box.
