Selective Precipitation of Value-Nonferrous Metals
Selective Precipitation of Value-Nonferrous Metals Components from the Slags Zhitong Sui Nianxin Fu Peixin Zhang Dept.of Nonferrous Metallurgy Northeastern University Shenyang 110006,P.R.China, Phone Number 86-024-3893000-7731 ABSTRACT The selective precipitation of B and/or Ti components was summarized, as examples of the
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
An Artificial Lightweight Aggregate Based on Non-ferrous
The investigations have demonstrated that granulated slags which are a by-product and are obtained through making non-ferrous metals, can be utilized as a basic starting raw material for manufacturing an artificial porous aggregate.
Review of Arsenic Pollution and Treatment Progress in
The arsenic emission from the process of metallurgy industrial production, which is main sources of Arsenic pollution, is harmful to environment. The treating methods and the present utilization of As-containing soil, slag and tailings, dust and As-contaminated wastewater are introduced in this paper.
Process Metallurgy School of Materials Science and
Process Metallurgy. Metallurgical engineering is based on the principles of science and engineering, and may be divided into process metallurgy, which is concerned with extracting metals from their ores to make refined alloys, and physical metallurgy, which involves the shaping, alloying, heat treatment, joining, corrosion protection and testing of metals.
Nonferrous Metallurgy Lead Smelting The most advanced lead smelting process is bottom-blowing lead furnace-smelting, and HollySys is the sole supplier for the control system of the bottom-blowing lead smelting process (SKS) of the China Nonferrous Design Institute.

This symposium provides a stage to introduce the advancements and developments of new high temperature metallurgical technologies and their applications to the areas of processing of minerals, extraction of metals, preparation of refractory and ceramic materials, sintering and synthesis of fine particles, treatment and recycling of slag and
Metallurgical Article about metallurgical by The Free
In this system metal processing is considered to be a part of process metallurgy and the mechanical behavior of metals a part of physical metallurgy. Process metallurgy, the science and technology used in the production of metals, employs some of the same unit operations and unit processes as chemical engineering. These operations and processes
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.
In order to surpassingly execute our mission, we offer a full range of technology services for non ferrous metal recycling and IBA processing to our customers and build long-term relationships. We are open and transparent about our investment options, yields, and earnings.
TECHNOLOGY FOR PROCESSING OF POLYMETALLIC MULTIPHASE SLAGS FROM NON-FERROUS METALLURGY INTO MINERAL RAW MATERIALS WITH SIMULTANEOUS RECOVERY OF METALS Polymetallic and multiphase slags are produced in smelting of the concentrates and semi-finished products in non-ferrous metallurgy (copper, zinc, lead, tin, silver). They contain 1-30% of non
slag are generated in the production of 1 ton of ferronickel. By now, slag has become the fourth largest industrial solid waste in China.2,3 Depending on the cooling methods, ferronickel slag can be classiﬁed into three types, namely, slowly-cooled slag, wind-cooled slag, and
Handbook of Non-Ferrous Metal Powders Technologies
Six prominent academics and industrialists from the Ukraine and Russia have produced this highly-detailed account which covers the classification, manufacturing methods, treatment and properties of the non-ferrous metals (aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, lead, tin, bismuth, noble metals and earth metals).
method of slag depletion should be stipulated not only by economic reasons, such as an enhancement of non-ferrous metals yield out of slag, but an ecological expe-diency of the taken decision as well, for example, the concomitant impurities removal out of the engineering process as non-toxic, easily-buried and/or utilizable compounds.
Project 1.2 K1-MET Metallurgical competence center
Beside LD slag, the current Project 1.2 considers other metallurgical slags from the ferrous and nonferrous production routes for a nearly complete closure of material cycles. Alternative utilization routes for ladle furnace slag and for slag from the copper refining process should
US20150000467A1 Method of separating and recovering
The present invention provides a method of separating and recovering iron from a waste non-ferrous slag, generated in a process for smelting of non-ferrous metals, including copper, zinc and lead, in which a reducing agent and a reaction catalyst are added to the crushed waste non-ferrous slag, and the mixture is subjected to a reduction reaction, thereby converting amorphous iron oxides
Industrial Process Profiles for Environmental Use Chapter
Alternate methods of bismuth refining are also in use involving wet chemical processing; these methods are not addressed in this report. 2. Input Materials The slag from the debismuthizing process is chiefly composed of ternary compounds of calcium, magnesium, and bismuth.
Non-ferrous metals, including aluminum, copper, lead, nickel, tin, zinc and others, are among the few materials that do not degrade and do not lose their chemical or physical properties during the recycling process. Consequently, nonferrous metals, and therefore precious metals, have the capacity to be recycled for an infinite number of times. 2.
Improving Copper Recovery from Production Slags by
The slag type used in copper industry is normally a fayalitic based slag . After processing the slag in the submerged arc furnace the slag still contains valuable metals. A typical slag composition including the main metal contents is given in Table 1.
