The material, which was tested in the and the need to protect all life forms. extraction of copper and lead ions from water, was applied in Several technologies have been proposed to treat wastewater column experiments to test its ability to preconcentrate copper contaminated with metal species.
The Copper alloy, with a grade of H68, is composed by 68% copper and 32% zinc (Zn). The Aluminum alloy, with a grade of 2A11, is mainly composed by Duralumin, and the trace elements contain –% copper, –% magnesium (Mg), –% manganese (Mn) and tiny amounts of silicon (Si).
Finely divided CuFeS 2 is concentrated by "Frothfloatation method". Crushed ore is suspended in water containing pine oil. A blast of air is passed through the suspension. The particles of ore get wetted by oil and floats as a froth which is skimmed.
Alloys using aluminum include alnico, which contains nickel, iron and cobalt; magnalium, which contains magnesium and duraluminium, also known as duralumin and duralium, which contains copper and, in some instances, magnesium and manganese. While manufacturers use alnico in the production of magnets, they use magnalium primarily in instruments.
Copper alloys include brass, bronze, cupro nickel and duralumin.. Brass is an alloy of copper (70%) and zinc (30%). Brass is harder and cheaper than copper.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
copper extraction decreases rapidly above 550˚C due to the decomposition of copper sulfate to other less soluble compounds. Tumen and Bailey   proposed this phenomenon as following reactions: ... Recovery of Copper from Copper Sulfide Concentrate by Sulfation Roasting
Duralumin, a key aluminium alloy, was invented in 1909. It took seven years for Alfred Wilm, a German scientist, to create it, but it was worth the years of effort. Duralumin, with addition of copper, magnesium and manganese was as lightweight, as aluminium, but significantly exceeded it in strength, hardness and elasticity meaning it quickly became the main material used in aviation.
Copper occurs both in native state as well as in combined state. The chief ore of copper are: Copper Pyrite (CuFeS2) Cuprite (Cu2O) Cupper Glance (Cu2S) Malachite [(OH) 2] Extraction of copper: Copper is extracted from is chief ore, copper pyrite. The various steps involved in the extractions are: a. Crushing and concentration: The [.]
