How to precipitate copper from the copper hydroxide - Quora
Answer (1 of 7): There are a number of ways of reducing copper compounds to copper metal starting with the hydroxide. Separate the copper hydroxide by filtration and washing and then heat in air to convert to the oxide according to Cu(OH)2 = CuO + H2O From hereon you have a couple of options. ...

Copper is considered the etiologic agent in the occupational disease referred to as "vineyard sprayer's lung". This disease, which is observed in vineyard workers spraying an antimildew agent containing 1– 2.5% copper sulfate neutralized with hydrated lime, was first described in humans by Cortez Pimentel and Marques (1969).

Add denatured alcohol to the solution until all the [Cu(NH3)4]SO4 precipitates. Filter the precipitate and add a little more alcohol to make it as free of water as possible. Water will cause the formation of copper(II) oxide when this is heated. Heat the precipitate until all ammonia has evaporated, leaving the white, anhydrous copper sulfate.

Chapter 6 Copper Production Technology
discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
