The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process).
COPPER PRODUCTION.Copper was first reported in Texas by Capt. Randolph B. Marcy in his exploration of the Red River in 1852. In 1864 a small amount of high-grade copper ore was smelted in Archer County; a part of this ore is said to have been used for percussion caps for the Confederate Army during the Civil War.After the war, Gen. George B. McClellan became interested in the copper .

average around US$66 million per year for copper blister and sulphuric acid exports. These would be in addition to current earnings of approximately US$140 million per year. The annual foreign exchange revenues over 30 years were converted into present value terms using a 4% base discount rate.
Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a "blister" copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.
Symptoms are expressed as smaller leaf size, chlorosis of the newer leaves, necrotic leaf tips, retarded growth of the entire plant, and/or reduced root growth. More often excess zinc found in the growing medium can compete with plant uptake of phosphorus, iron, manganese or copper and can cause their deficiencies in plant tissue.
The company also operates Buenavista, an open-pit copper mine, as well as two copper concentrators and three SX-EW plants in Mexico. In addition, it operates five underground mines that produce zinc, lead, copper, silver, and gold; a coal mine that produces coal and coke; and a zinc refinery.
Raw material of this process is blister copper, copper ingots and scrap copper. Fire refining takes place in THOMAS type furnaces at about 1250 o C. Refined molten copper which has 99.5% copper purity is poured into anode molds with a tolerance of ± 1 kg by using PLC controlled automatic casting system.

Copper is a constituent of the enzymes oxidases and of the protein plastocyanin in plants. In optimum concentrations, copper increases the resistance of plants to cold and promotes growth and development. Among animals, some invertebrates contain large amounts of copper (mollusks and crustaceans contain 0.15-0.26 percent copper in the hemocyanin).
