Copper Mining and Processing: Processing of …
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Fundamentals: Types of Copper and Properties
Types of Copper and Properties. The copper most commonly used for sheet and strip applications complies with ASTM B370. It consists of 99.9 percent copper, and is available in six tempers designated by ASTM B370 as: 060 (soft), H00 (cold rolled), H01 (cold rolled, high yield), H02 (half hard), H03 (three quarter hard), and H04 (hard). Soft temper copper is extremely malleable and best suited ...
Copper Ore Processing Methods
general adoption of flotation process, influencing the development of the reverberatory furnace, which generally has replaced the blast furnace in smelting operations, with resultant benefits in the cost of copper smelting. Types of Ores & Methods of Treatment. From the milling standpoint, copper ores may be classified roughly as follows:
Metal Types and Recycling Process
When the products made of these metal bars come to the end of their useful life, the metal recycling process cycles again. Challenges for the Metal Recycling Industry The current overall metal recycling rate of around 30 percent is not acceptable, given the recyclability of almost every kind of metal, and challenges remain with respect how to recapture more material for recycling.

COPPER Copper production - Repository
Smaller types of blast furnace, however, are used to process such copper-containing materials as intermediate products (e.g., cement copper or copper(I) oxide precipitates), reverts (e.g., converter slag, refining slag, or flue dusts), and copper-alloy scrap. The construction of the furnace is basically related to that of the iron blast furnace, but there are considerable differences in design ...
Copper - Sulphuric Acid
Seventeen copper smelters world wide utilize Outokumpu flash smelting. Historically this process uses fuel and preheated air to supplement the heat generated from the exothermic oxidation of CuS. A medium-grade matte of 45% to 50% Cu is produced. Oxygen-enriched process air can be used resulting in a high-grade matte (65% to 70% Cu) under autogeneous conditions. The Kennecott Smelter in Utah ...
