Environmental Product Declaration Gerdau Rebar, Midlothian

Environmental Product Declaration Gerdau Rebar, Midlothian Steel Mill PRODUCT SCOPE This EPD is for Carbon Steel Rebar that is obtained from steel scrap that does not contain material. Scrap metal, together with alloying additions, are melted in an Electric Arc Furnace (EAF) to obtain liquid steel and casted into steel billets.

Recovery of manganese from steel plant slag by carbamate The U.S. Bureau of Mines investigated the feasibility of using ammonium carbamate (NH2CO2NH4) leaching to recovery manganese from steel plant slag. This investigation showed that treatment of the slag in hydrogen prior to leaching enhanced manganese extraction.

Pickling is a unit operation within stainless steel production, which means treating the steel with hydrofluoric acid (HF) and nitric acid (HNO3), also called mixed acid. The whole process generates waste water streams which have to be treated before released to recipient.

Gore produces a wide range of filter bags that vary by material and resistance to temperatures, moisture, oxygen, acid and alkali. In steel, ferroalloy and non-ferrous metal plants where manufacturers need to weigh EPA regulations against production needs, we recommend GORE LOW DRAG Filter Bags. With the lowest filter resistance of all filter

Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid
