To make a door, I need 2 Copper Bars, and to make them, I need Copper Ores. How can I find some Copper Ores? I had some in my inventory so I don't think that it is a quest reward etc. but I think that it is a drop from monsters or a spawn underground as an ore.

Copper processing

Copper processing - Ores, Refining, Smelting: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value …

Extraction of Copper: Detailed Process

Smelting, leaching, and electrolysis are used to extract copper from these ores and minerals. Chile, Peru, and China are the three biggest copper-producing countries. It is found in both its native and combined states. The principal copper ores are: (i) Copper glance; Cu 2 S (ii) Copper pyrites; CuFeS 2 (iii) Malachite; Cu(OH) 2 CuCO 3

Current Status of Copper-Ore Processing: A Review

IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is

Copper in the Crust | Science

The concentration of most metals is extremely low in Earth's crust. For copper, the most important ores globally are the porphyry deposits, which form when copper and other metals are concentrated in fluids emanating from and flowing through shallow bodies of magma in the crust. Rapid cooling of these fluids, or a sudden change in their chemistry as they interact with …
