PURPOSE: To efficiently reutilize resources, to form an effective recycling line and to recover hydrochloric acid and copper sulfate by separating and recovering the useful hydrochloric acid and copper sulfate from a waste copper chloride soln. discharged from an etching stage.山田 慶太...
Hydrochloric acid is often used to dissolve solid samples for further analysis, including dissolving some metals and calcium carbonate or copper oxide to form easily soluble substances to facilitate analysis. 5. Pickling steel One of the most important uses of hydroch...
Production of zinc oxide from complex sulfide concentrates using chloride processing hydrochloric acid and oxygen to produce a leach solution; precipitating iron from the leach solution with magnesium oxide; recovering at least one of copper, silver, cadmium, cobalt and lead from the leach solution by...

The Anodic Dissolution of Copper in Hydrochloric Acid Solutions. The electrodissolution of copper in hydrochloric acid solutions at the rotating ring-disk electrode was found to be controlled by both mass transfer and reaction in the apparent-Tafel region in HCl concentrations of between 0.1 and 1.0...
It appears light yellow when it contains traces of iron (iron oxide), free chlorin e or organic matter. Strong acid, can be mixed with water and ethanol in any ratio. Strongly corrosive, can be neutralized with alkali, and has no effect with phosphorus, sulfur and other non...

. It is also used to pickle metals, i.e. clean the surface prior to electroplating. Hydrochloric acid donates protons with ease and is the strongest of the hydrohalic acids. The concentrated acid is oxidized to chlorine by such agents as potassium manganate(VII) and manganese( IV) oxide....
