The process used to treat sulfide copper ores begins at the mine site, where the copper bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
Copper Mining and Processing: Processing of Copper Ores
A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.
The acid consumptions curves for the oxide copper ore (number 3) with a high iron oxide tactile gangue were somewhat different than those of oxide copper porphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.
CopperFrom Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper tin alloy) about 3000 BC, was the first engineering material known to man.
Types of copper ore: Oxides. As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. However, in some cases low grade copper oxide ores can still be economically mined because they can be processed at a lower cost than copper sulfide ores.
29/3/2017· Copper is one of the top seven metals known since the ancient time. Actually, humankind knows over 170 copper containing minerals. Copper melts at 1,0830C. Copper and zinc alloy is known as brass. Copper and tin give us
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed and ground to liLive Chat
