The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte. All but one U. S. smelter uses Pierce-Smith converters, which are refractory-lined cylindrical steel shells mounted on trunnions at either end, and rotated about the major axis for charging and pouring.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

BF slag.5 Using slag prevents it going to landfill as waste, for waste water treatment, and in coastal marine blocks that encourage coral growth. Previously landfilled as useless co-products, slags are now recognised as marketable products. Gases, dusts and sludges Gases from iron- and steelmaking (for example, from the coke oven, BF or BOF) once cleaned, are used internally to produce
and treatment method using a rotary cooler as the main equipment. 2.2 Studies on slag treatment process Two types of slag stem from iron- and steelmaking processes: blast furnace and steelmaking slags. Various methods for granulat- ing blast furnace slag using water were developed since the 1970s, and its use as blast furnace cement rapidly expanded.5, 6) Meanwhile, mainly for converter slag

A device to treat molten steelmaking slag comprising: a closed chamber, the closed chamber including: a solidification device able to produce solidified slag particles having a diameter inferior or equal to 1 mm; a bottom porous wall; and at least three gas injectors. 47. The device as recited in claim 46 further comprising an exhaust gas collector and a gas recirculator. 48. The device as
The residual slag in the converter is conditioned for chemical composition and temperature after tapping and is splashed by a violent nitrogen flow around the converter wall. The procedure itself, as well the consequences to the converter process, are fairly complex and the slag should be strictly adjusted for the treatment. Slag is to carry out several tasks during the steelmaking process in

treatment in ladle furnace. This process produces slag with only small variations in composition and properties. The aim of the work presented in this contribution was to study the possibilities of EAF slag recycling into the refining – remelting process in EAF and to recognize all possible positives and negatives of the recycling. Though electric arc furnaces used in foundries producing
01.01.2001· The converter slag was obtained as small particles from air filters of the Bessemer Converter . This slag is inexpensive and abundant, and is therefore ideal for low-cost wastewater treatment. It is a solid waste and can be used as an adsorbent, prior to eventual discharge of effluents with heavy metal content under permissible limits and thereby adhering to environmental regulations.
Ferrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is

The high roasting temperature and low leaching efficiency of vanadium from vanadium-bearing converter slag are regarded as the main factors significantly influencing the application of calcification roasting–acid leaching processes in the cleaner production of vanadium. In this study, a mechanical activation treatment was performed to enhance the extraction of vanadium from converter slag.
NATIONAL SLAG MF 205-1 ASSOCIATION Page 1 Water Improvement Initiatives in New Zealand Using Melter Slag Filter Beds Bill Bourke, SteelServ Ltd, Auckland, New Zealand ABSTRACT The ability of iron and steel industry slag aggregates to remove phosphorous and certain heavy metals from degraded water has been understood and well researched for many years (e.g. Yamada et al.1986). Aggregates
Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
ISD DUNAFERR Zrt. produces blast furnace slag and converter slag as a result of its metallurgical activity.
