Abrasive blasting - Wikipedia

Abrasive blasting - Wikipedia

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the media).

The Extraction of Copper - Chemistry LibreTexts

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas.

This metallic lead in liquid state traps gold and silver. As slag and metallic charge have different densities, lead and precious metals go to the bottom of the crucible and the slag floats. In other words, lead reduces the losses of precious metals into the slag. The mixture of heat, fluxes, carbon and lead assure an appropriate reducing .

Smelting - Wikipedia

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
