Gold-copper ores
The treatment of a copper sulphide-bearing gold ore by direct cyanide leaching, ammonia pretreatment and ammoniacal cyanide leaching was investigated. Dissolution behaviour of gold and copper in these leaching systems was demonstrated. Severe interference by the copper containing sulphides with cyanide leaching of gold is observed at ρ(NaCN ...

Copper Ore | Items | Terraria Checklist | Track your journey
Copper Ore is an early game ore, which spawns on the surface as well as in the Underground and Cavern layers. It is the weakest and most easily obtained tier of ore in the game. Its primary use is to make Copper Bars, which can be used to create the Copper tier of equipment.The equivalent of Copper Ore is Tin Ore, which will sometimes replace Copper in a world.

Innovations: Introduction to Copper: Mining & Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
