In the first step, the raw slag was crushed into pieces with a size of less than mm. Some raw slag samples were taken for analysis and detection, and the remaining slag was mixed with additives for reduction–sulfurization smelting. In the second step, the modified slag obtained after reduction smelting was crushed to less than mm.

 · oxide from those other elements, reaching a more valuable product for zinc smelter (>98% ZnO+PbO). The unfumed material (iron mainly metalized) leaves the furnace at °C, it is extracted through a watercooled screw and then recycled as ironunits to steel industry; or quenched in water before disposal.

dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption. The present work shows that .

Two tapholes were used to tap metal and slag separately. Lined and cast iron ladles were used for containing metal and slag, respectively. Process control and data logging were managed through the Delta V control system. DC Furnace Furnace slag Furnace alloy Electrode hoists and clamps Fume collection Bag filter plant Stack Batching plant Main Conveyor Selector valve 1 2 .

Slag and iron are tapped from the furnace at 1750°C and 1450°C respectively. The circular furnace has two slag tapholes and two iron tapholes. Two claygun units rotate around the taphole area of the furnace, and can be used to drill and plug all four tapholes. The three products from the furnace follow different processing routes: Gas The CO gas produced by the furnaces passes through the ...

final slag (less than %), but iron and silicon existing, as iron oxides and silica, remain approximately the same. The molybdenum is high enough to make its recovery of interest. Table 1: Composition of a Chilean Copper Smelter Slag Slag Treatment Composition (wt%) .

Slag aggregates are obtained by crushing of smelter slag or by special treatment of fireliquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding component and as fillers. Slag, generally classed as a synthetic aggregate (also called artificial aggregate), is produced by ...

Slag generally comes from factories such as cement plants, thermal power plants, smelters, etc., mainly from the following sources: ① Oxides formed by oxygenation of various impurity elements (such as Si, Mn, P, etc.) contained in iron and steel (hot metal, scrap).

Iron ores are rocks and minerals rich in iron oxide that can produce metallic iron when smelted. Due to the nature of the iron oxide present in iron ore, they can range in color from dark grey to a deep red. The iron in such ores is commonly found in the form of magnetite, hematite, goethite, limonite, and siderite.

28/11/2011 · By contrast, the lower fuel methodology dissolves all the ore to the slag before reducing available FeO to metal out of the slag. The major downside of this methodology is that it relies on having a very rich ore as much slag is created and there is the risk of loosing considerable iron to the slag.

There exists a demand for improved and less costly control methods of lead from smelter slag and matte, that allows for infurnace Pb stabilization thus reducing expensive postfurnace slag handling, permitting, monitoring, crushing and stabilization appliion. The present invention discloses an inline Pb smelter slag and matte control method through contact of waste with .

D. Zhu, in Iron Ore, 2015. Background. Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke ...

method. More recently, there has been a great deal of interest expressed in the recovery of cobalt (often together with nickel and copper) from a variety of slags because of the obvious economic impliion [3]. However, with the increasing of oxygen enrichment during smelting, copper and cobalt in smelter slag increasingly are lost in fayalite and magnetite in form of oxydic dissolution and ...

Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron ...
