The relative ability of a ferrous metal to form martensite when quenched from high temperatures. Hot Rolling A process used in steelmaking that reduces the thickness of an ingot, billet or stab using pressure with the material being rolled at an elevated temperature.
In the production of steel and non-ferrous metals, borates act as a flux during smelting. In this capacity, they are used to dissolve metallic oxide impurities, which are then removed with the slag. Borates are also used as a cover flux, to provide a protective barrier against air oxidation.
Mar 07, 2018· Ferrous metals by definition contain iron in them whereas non-ferrous metals do not contain iron. The word iron is derived from the Latin word ferrum, hence the English derivation ferrous to describe iron bearing metals.. The main thing to know about metals is whether they are ferrous or non-ferrous. Once we have made the distinction, we can look at their different properties.
Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

Non-Ferrous Metal Industries: Present Status & Proposed standards . Content • Company Profile • Introduction • Production of Non-Ferrous Metals in India • Primary slag containing iron sulphides, silica Electrolytic Copper Refining Treatment • Fabric filters are used to control particulate emissions.
Non-ferrous metallurgical processing Lime is also important for the pyrometallurgical refining and smelting of several non-ferrous metals. In addition, lime products are used in effluent and tailings treatment, and in settling, dewatering, filtration, environmental protection and mine safety.
Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags.
Electro-refining. Usually the object of electrolytic refining is to separate one metal in pure form from an alloy containing a high percentage of the desired metal, copper for instance, and a number of other metals dissolved in the copper or intimately mixed with it.
Metalcess provides process and engineering design and related equipment for non-ferrous metal metallurgy including copper, lead, zinc, tin, precious metal, etc. We offers non-standard equipment especially for mini-scale project. ... Tin slag reduction and refining . ... Whatever the approach is, high iron content in less amount slag/residue ...
Nonferrous slags are produced during the recovery and processing of nonferrous metal from natural ores. The slags are molten by-products of high temperature processes that are primarily used to separate the metal and nonmetal constituents contained in the bulk ore. When cooled, the molten slag converts to a rocklike or granular material.
In smelting, the worthless material, usually iron, forms a slag with fluxing material and is converted into the oxide. The valuable metals acquire the metallic form at the converting stage, which takes place in converting furnaces. ... Most non-ferrous metals can also be refined by electrolysis. ... Smelting and Refining Operations Metal ...
PRETREATMENT OF RAW MATERIALS Definition statement ... produce non-ferrous metals and compounds thereof [N: Methods of a general interest or applied to the winning of ... Diverse methods for refining metals in liquid state (C22B 9/003 to C22B 9/106). Refining metals in …
Some non-ferrous materials are also used in the iron and steel industries. For example, bauxite is used as flux for blast furnaces, while others such as wolframite, pyrolusite and chromite are used in making ferrous alloys. Important non-ferrous metals include aluminium, copper, lead, nickel, tin, titanium and zinc, and alloys such as brass.
Non ferrous slags make up only 12% of the total annual production Described below are the main types and uses of slag commercially available in Ferrous Slag products. Iron Blast Furnace Slag (BFS) This is the co-product from the reduction of iron ores to produce molten iron and molten slag. 1.
Technical distribution of metals includes groups of metals with significantly different physical and technological properties. From a technical point of view, metals can be distributed into two groups: 1. Iron and its alloys and 2. Non-ferrous metals. The numerous group of non-ferrous metals is further divided into several sub-groups.
REFINING OF NON-FERROUS METALS J. G. BERRY-Abstract The fundamentals of refining of non-ferrous metals have been outlined. Examples of removal ... Iron is readily removed in the slag, as also is aluminium. Arsenic and antimony, if pre-sent, are removed by using soda-ash and lime,
Ferrous metals are those which have the iron as their main constituent, such as pig iron, cast iron, wrought iron and steels. Non-ferrous metals are those which have a metal other than iron as their main constituent, such as copper, aluminium, brass, bronze, tin, silver zinc, invar etc. Classification of engineering materials FERROUS METALS ...
Sep 23, 2015· Wrought iron is used for fencing and railings, agricultural implements, nails, barbed wire, chains, and various ornaments. Which Metals Are Non-Ferrous? Non-ferrous metals include aluminum, copper, lead, zinc and tin, as well as precious metals like gold and silver. Their main advantage over ferrous materials is their malleability.
Blast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
Operating as a batch melting process, the charge materials used for melting are steel scraps, sponge iron, DRI and other such materials, either alone or in combination. Refractories used in this vessel are exposed to high temperatures which are most severe in the hot spot zones.
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity.
The product (ZORBA) of the non-Fe separator is a valuable input for all manner of non-Fe metal recovery plant as a means of separating and recycling the non-Fe metals contained. Customers for non-Fe products include dry mechanical process operators, manual sorting plant, wet mechanical systems and secondary smelting operators.
