Recovery of valuable metals from copper slag | SpringerLink
The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation roasting–sulfate …

Make Copper Powder From Aluminum Foil
Step 1: Dissolve Copper Sulfate in a Cup of Water. Dissolve one ounce (28 grams) of blue crystals of copper sulfate in one cup (250ml) of warm water in a clear jar. You may have to stir it for several minutes. Copper sulfate is somewhat toxic, so don't touch it, drink it, or pour it on yourself. And definitely don't splash it into your eyes.

Should I use aluminum sulfate (sulphate) to acidify my soil?
Aluminum sulfate acidifies the soil because of the sulfate, not the aluminum. Actually, its possible aluminum, being Al+++, could take the place of 3 hydrogen ions (H+), though more likely is it would take the place of a Ca++ and 1 H+. Anyway, its the sulfate which causes acidity. SO4 + 2 H2O = 2 H2SO4 + O2. Sulfate + water = sulfuric acid + oxygen

Preventing Metal Corrosion with Metalworking Fluids
Heat removal is one of the most important functions of a metalworking fluid. Effective heat removal yields good tool life and dimensional accuracy of parts. Water has a greater capacity for removing heat than oil; however, water alone in contact with freshly machined metal leads to corrosion. Thus, corrosion is a problem faced by every user ...

The Use of Alum for Lake Management
Alum is applied to lake water as aluminum sulfate, or Al 2 (SO 4) 3 · 14 H 2 O. As aluminum sulfate is added to water, it forms aluminum ions, which are hydrated (combined with water): Al +3 + 6 H 2 O ⇄ Al (H 2 O) 63+. In a series of chemical hydrolysis steps, hydrogen ions are liberated, which may lower the water pH, and ultimately forms ...
