Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.Get Price

Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250 C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.Get Price

Copper tube for air conditioning and refrigeration field service (ACR) is designated by actual outside diameter. Temper describes the strength and hardness of the tube. In the piping trades, drawn temper tube is often referred to as hard tube and annealed as soft tube.Get Price
The material can be cold worked or formed in this condition. A lower temperature spinodal decomposition treatment, commonly referred to as ageing, is then used to increase the hardness and strength of the alloy. Spinodal hardening alloys are basically copper nickel alloys with chromium or tin additions.Get Price
Jan 05, 2021 Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.Get Price
Geologic Occurrence. Azurite is a secondary mineral that usually forms when carbon dioxide laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment.Get Price
