Benefits of sensor-based slag metal sorting at a glance: Free metal recovery: Separating non-magnetic metallic particles effectively means earning revenue at low cost. Disseminated metal concentration: Concentrating metal containing slag particles before it undergoes separation, through crushing and jigging, protects crushers at little expense.
Oct 18, 2019· Finally, ten experts presented current projects on the topic of "Research and innovation", including the further optimisation of slag-based products. "The 10th Euroslag has shown that the use of ferrous slag in building materials and fertilisers in Europe is an important building block for economic and ecological management.
Ferrous lags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper, lead/zinc) depending on the industry from which they come. Depending on the iron and steel production process different slag types can be manufactured like blast furnace slag, basic oxygen furnace slag, electric arc furnace slag, secondary metallurgical ...
Ferrous Slag – general information. Iron and steelmaking slags (ferrous slags) are co-products of the iron and steel making industry. They are non-metallic rock-like materials which are produced together with the metallic products of these processes.
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.
3. Non-ferrous slag. There are a variety of non-ferrous slags produced from non-ferrous smelters. Extensive studies on metal recovery from non-ferrous slags have been carried out for the past decades. Most of the studies were on metal recovery from copper slag.
Jun 08, 2018· Greek holding Mytilineos has announced that it will invest EUR 33.8 million (US$40 million) to build a slag processing and recycling plant in Romania, where it owns a lead and zinc smelter. The new facility will be built next to the existing non-ferrous metal plant Sometra, at Copsa Mica, in ...
Description of the Slag Samples Different slag samples were obtained from non-ferrous smelting operations. Their compositions are for the oxygen potential determining constituents are listed in Table 1. Slag 1 was obtained from a lead blast furnace operation. Slag 2 is a cleaned lead blast furnace slag. Slag 3 is a reduced lead blast furnace slag.
Another major difference in non-ferrous extraction is the greater emphasis on minimizing metal losses in slag. This is widely due to the exceptional scarcity and economic value of certain non-ferrous metals which are, inevitably, discarded during the extraction process to some extent.
Copper Slag is a non‐ferrous blasting abrasive that features low dusting, and low free silica content. Coal Slag. Coal Slag is a non‐ferrous, chemically inert, blasting abrasive that features low dusting, and low free silica content. Steel Grit. Cast angular grit is produced by …
The conference will allow all attendees to maximise their profits from slag - both ferrous and non-ferrous, will keep them up-to-date with the industry state-of-the-art and will provide extensive networking and business opportunities for both producers and users of slag and slag-based products.
Improved slag from non-ferrous metal production FIELD OF THE INVENTION The present invention relates to the production of non-ferrous metals, such as copper, from primary sources, meaning fresh ore, from secondary feedstocks, also known as recyclable materials, or from combinations thereof.
Heavy and non-Fe metals can be melted down, time after time. They are thus ideal for recycling. An important role here is played by the quality of the processed, sorted metals to ensure their use in the smelt and to achieve value creation and marketing assurance. Non-ferrous metals find uses in all areas of industry and in consumer goods.
Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag has a long history. The broken slag from ironmaking was already REUTER, M., XIAO, Y., and BOIN, U. Recycling and environmental issues of metallurgical slags and salt fluxes. VII International Conference on Molten
The mining industry consumes 2%-3% of the world's energy. That's the same amount of energy used by the entire airline industry. Our sensor-based sorters can reduce that energy consumption by 15%, as well as reduce the amount of water used by three to four cubic meters per ton of ore.
A non-ferrous slag from the production of metallic zinc was studied as a new ingredient for concrete. It was used in two forms: ground and un-ground material. The ground slag replaced 15% of portland cement, whereas the un-ground slag replaced 20% of the natural sand.

The Future of Non-Ferrous Slag: Market Forecasts to 2027 identifies some typical end uses for the non-ferrous slag residue, mainly in road construction and buildings, as well as substitutes for sand in sandblasting processes. The range of potential applications is gradually expanding as a result of research projects into the suitability of using.
Each slag type usually contains a specific suite of elements that may be of environmental concern. In general, non-ferrous slag may have a higher potential to negatively impact the environment compared to ferrous slag, and is thus a less attractive material for reuse, based on trace element chemistry, principally for base metals.
Slag from non-ferrous metal smelting ...
Nonferrous Slags - Material Description ORIGIN 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 …
Slag from the non-ferrous metallurgy is rich in Fe. This is the main difference with Portland cement and conventional precursors for alkali-activated materials and the main source of complexity. Fe can have several oxidation states (Fe 2 and Fe 3 ) and structural arrangements ...
Slag recycling. With smelting slags, two approaches are available in principle for recycling. Recovery of the ferrous and non-ferrous metals and also the use of the pure, metal-free slag itself as a secondary construction material.
Oct 01, 2019· Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.
In 2019 production volumes of non-ferrous slag will be over 116.4 million tonnes worldwide. This new study tracks and critically analyses how this market will develop across the next ten years, with forecast growth at 1.0% CAGR to reach 133.7 million tonnes in 2029.
Slag and dross, which occur in significant amounts in every metallurgical process, have a very bad reputation as partially hazardous residues. Often rightly so, since the high heavy metal content does not allow its use as a mineral product.
In Canada, where nickel slag is used in fill applications, it is common practice to provide a layer (typically 150 mm (6 in) thick) of natural aggregate between ferrous materials and the slag. (15) Hydratable oxides may also be present in some nonferrous slags from some sources, which could potentially contribute to volumetric instability.
Sep 23, 2015· The simple answer is that ferrous metals contain iron and non-ferrous metals do not. The more in-depth answer is that ferrous metals and non-ferrous metals each have their own distinctive properties. These properties determine the applications they are most suited for. Non-ferrous metals have been used since the beginning of civilization.
About 87 kg of non-ferrous smelting slag samples were collected during the above-described archaeological excavations (the amounts of various types of slag materials and their location are indicated in Fig. S5 and S6 in the Supplementary Data). The slags were mainly found in the fills of houses, in pits or in settlement layers; often in ...
