Aluminium + copper (II) sulfate → copper + aluminium sulfate. Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. This allows a simple exchange reaction with the copper (II) sulfate. The protective oxide layer forms instantly the aluminium is exposed to the ...

Modern bullets are no longer balls and are made primarily from lead and copper/copper alloys. Because of barrel fouling lead bullets usually have a 'jacket' around them made of a harder material like copper/copper alloy. For this article we'll refer to these two primary bullet types as lead core and copper bullets.

Converters (Figs. 50–53) are used in steelmaking, in copper production and to a limited extent in other non-ferrous processes. Air is blown through or over the top of the molten charge, reacting with part of it to produce sufficient heat to maintain the process. In steelmaking the heat is derived from the oxidation of the elements silicon ...

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
