The EPA started a short-term cleanup in fall of 2011, removing 233 drums of industrial waste and 6,100 gallons of chromium-contaminated water from the site. From 2012 through 2014, the EPA demolished the E.C Electroplating building, and contaminated soils and concrete from the site were excavated and removed.
The Alabama Plating Company Superfund site is a former industrial site in Vincent, Alabama. The site covers 6 acres and was used by the Alabama Plating Company as an electroplating facility between 1956-1986. The facility caused contamination of the ground water with hazardous waste containing heavy metals. [2]
Wastewater from metal mines and ore recovery plants are inevitably contaminated by the minerals present in the native rock formations. Following crushing and extraction of the desirable materials, undesirable materials may enter the wastewater stream. For metal mines, this can include unwanted metals such as zinc and other materials such as ...
Plating equipment evolved from manually-operated tar-lined wooden tanks to automated equipment capable of processing thousands of kilograms per hour of parts. One of the American physicist Richard Feynman's first projects was to develop technology for electroplating metal onto plastic. Feynman developed the original idea of his friend into a ...
Simple scheme of the apparatus for electro-oxidation process. The set-up for performing an electro-oxidation treatment consists of an electrochemical cell.An external electric potential difference (aka voltage) is applied to the electrodes, resulting in the formation of reactive species, namely hydroxyl radicals, in the proximity of the electrode surface.

Some sources of lead pollution in the environment include Metal plating and fishing operations, soil waste, factory chimneys, smelting of ores, wastes from batter industries, fertilizers and pesticides and many more. Unlike, other metals such as copper, lead only plays a physiological aspect and no biological functions.
Electrowinning, the extraction of metal from ores [2] Electrorefining, the purification of metals. [2] Metal powder production by electrodeposition is included in this category, or sometimes electrowinning, or a separate category depending on application. [2] Electroplating, the deposition of a layer of one metal on another [2]
Electrochemical coloring of metals is a process in which the surface color of metal is changed by electrochemical techniques, i.e. cathodic or anodic polarization. The first method of electrochemical coloring of metals are certainly Nobili's colored rings, discovered by Leopoldo Nobili , an Italian physicist in 1826.
