Dephosphorization of chromium-rich ashes from thermally ...

 · For chromium-rich ash to be employed as a raw material in a pyrometallurgical process, the produced ferrochromium alloy must have an adequate phosphorus content. For this reason, a simple mass balance of ferroalloy production was performed, aiming to determine the minimum phosphorus removal percentage that should be achieved for ash utilization.

chrome production is on the upswing. The mining of these chrome seams is by conventional scraper-winch and hand held drill rigs where the seams are less than 1.5 meters in width and by more mechanized drill rigs and LHD''s where the reef width or combination of closely associated reefs is greater. The mining layout is typically bord and pillar ...

Chrome plating

Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. The product of chrome plating is called chrome.The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.

Copper Production

 · Abstract. Section 2.1.1 covers the basic thermodynamic and kinetic principles involved in producing copper by high-temperature smelting processes. The section starts with the description of the stability of copper compounds relevant to the pyrometallurgical production of copper from the minerals and how it relates to the development and operation of different production methods.

NICKEL RECOVERY FROM ELECTRIC ARC FURNACE SLAG BY …

During the pyrometallurgical treatment of the nickel-bearing laterite in the plant of G.M.M. S.A. LARCO, slag is produced after treatment in electric-arc furnace (EAF) that contains 0.10 to 0.20 % Ni. Taking into account the great quantity of slag produced per year, the recovery of nickel from the EAF slag will add benefits to the entire process.

Converting Process

 · Normally 0.5–2.0% copper is considered satisfactory for copper extraction by concentration followed by a pyrometallurgical process that treats concentrates with 24% copper or higher, or is extracted by a hydrometallurgical process that handles lower-grade copper ores (Ray et al., 2014). Recycled scrap is becoming a source of copper production.

Metal losses in pyrometallurgical operations

 · In a pyrometallurgical process, several phases can be present besides the liquid metal: slag (mixture of metal oxides), matte (mixture of metal sulphides), etc. The slag mainly contains the gangue ores, from which the metal is extracted, and is mostly used to remove certain impurities.

WO2018189154A1

Disclosed is a pyrometallurgical process for producing a crude solder from a feedstock selected in terms of its levels of Sn, Cu, Sb, Bi, Zn, As, Ni and Pb, the process comprising at least the steps of obtaining in a furnace a liquid bath of metal and slag, introducing a reducing agent and optionally also energy, separating the crude solder from the slag and removing liquid from the furnace.

New Trends in Submerged Arc Furnace Technology

FeCr production is carried out either in DC or AC based SAF. The increasing share of fine ores in the mine bodies of newly explored mines might force the ferro chrome producer either to agglomerate the ore or to process it directly as fines. A common way of charging fines to the SAF is via a hollow electrode system (HES), which had first been
