The trademark of a special type of coil-coated steel sheet with plastic and zinc dust coating, which is proving increasingly useful in automobile manufacture.

OBS

Another corrosion-resistant coated-steel product involving zinc is Zincrometal (Metal Coatings International), which is processed with a proprietary, two-coat system. The base coat is a chromium-base inorganic material called Dacromet. After the coating is baked, the coil is coated with a second material - Zincromet, an epoxy-based, zinc-rich topcoat - followed by another baking cycle.

High levels of zinc deposition from the stack dust has decimated the landscape along parts of the Appalachian Trail that skirt the smelter.

CONT

However, analysis of stack dust from one of the nickel-copper smelters in the Sudbury area by Cox and Hutchinson (1981) indicated that 77% of the particulate nickel was in water-soluble forms.

CONT

Electric Arc Furnace Dust(EAF Dust) is the airborne dust generated in the steel manufacturing process when metal scrap is electrically melted. It is typically only about 1. 5% of the output from a typical mini-mill, but creates an environmental problem which must be handled intelligently. The material is a calcium iron silicate with contaminants of heavy metals such as lead, zinc, cadmium, chromium and others.

CONT

In a typical electric arc furnace(EAF) operation for melting iron-containing scrap, approximately one to two per cent of the charge is converted into dust which is collected in the baghouse. These EAF dusts have been classified as hazardous wastes due to their lead, cadmium and hexavalent chromium contents; however, these dusts also contain large quantities of zinc and iron whose recovery is economically attractive.

French

Domaine(s)
  • Fonderie
  • Agents de pollution
CONT

Lors de l'opération typique d'un four à arc (EAF) pour la fonte de rebut contenant du fer, approximativement 1 à 2 % de la charge est convertie en poussière qui est récupérée par l'unité de filtration. Ces poussières du four à arc ont été classées comme déchets dangereux à cause de leur contenu en plomb, en cadmium et en chrome hexavalent; cependant, ces poussières contiennent également de grandes quantités de zinc et de fer dont la récupération est économiquement intéressante. Dans le présent travail, on a traité, en vol, de la poussière de four à arc ayant un contenu élevé en zinc [...]

English

Subject field(s)
  • Mineral Processing (Metallurgy)
  • Processing of Mineral Products
DEF

The extraction of gold and silver from their ores. The process is only applicable to these metals. The solvent is a weak solution of sodium or calcium cyanide which, when aerated, easily dissolves the precious metals. They are then recovered by agitating the "pregnant" solution with aluminium or zinc in the form of dust or shavings and filtering out the precipitate which is then melted and cast into bars(bullion).

French

Domaine(s)
  • Minéralurgie (Métallurgie)

DEF

Traitement des minerais d'or et d'argent que l'on dissout dans des solutions très étendues de cyanures alcalins, en présence de l'oxygène de l'air, et dont on précipite ensuite les métaux précieux par le zinc ou par l'électrolyse.

CONT

Or associé à des sulfures de fer. [...] son extraction nécessite un processus [...] comportant en général une préconcentration et une calcination des concentrés, suivies de cyanuration.

CONT

L'essor industriel [...] du Witwatersrand commença [...] quand on employa la cyanuration pour recueillir le métal précieux.
