Electrolytic Rust Removal Aka Magic: This is a relatively simple, safe and cheap way to remove light or heavy rust from any ferrous object. I used this process to restore an old wood plane that I bought for $1 (it looked totally un-usable because of the rust). As opposed to grinding,...

Silver and gold are commonly refined electrolytically—a neutral silver nitrate solution is the electrolyte for silver refining, and gold chloride solution for gold refining. Precious Metals The anodes used in refining base metals — nickel, copper, lead—by electrolysis usually contain gold, silver, platinum, palladium, etc., as well as selenium and tellurium in some amount.

Method diagram Method and installation description . The aim of precipitation is to precipitate the chemical from dissolved substances in the wastewater by adding a reagent, which forms an insoluble compound with the to-be-separated matter. Positive ions such as (heavy) metals, but also negative ions like phosphates and sulphates, can be removed via precipitation. In general, precipitation ...

Electroplating Wastewater Treatment System Process Description. Electroplating wastewater comes from surface plating operations where the metal is dipped in an electroplating solution of various types of metals and then rinsed. Typical plating includes brass, nickel, cadmium, zinc, silver, copper, and gold. Electroplating wastewater is typically from washing, rinsing and batch dumps and is at ...

Cuprous copper requires 0.44 lb. pure iron per pound of copper for precipitation. 37.8 x 0.80 ÷ 0.44 = 68.7 tons copper precipitated. This gives a comfortable margin of SO2 for precipitation and any excess can be easily wasted. The above calculation is rather rough, because, as before mentioned, the complete data of the sponge iron process are not yet worked out, but it is probable that it is ...
