Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
Fayalite is the main phase of copper slag and a type of Fe silicate glass that is composed of a polymerized network of silicate tetrahedrons in which SiO 2 and FeO are generally considered as network formers and modifiers respectively The structure of fayalite is shown in Fig 13 [107] In iron silicate glass O 2− exists in the form of bridging and non bridging oxygens BOs and

·Copper slag is composed of iron silicate obtained by smelting copper concentrate and silica flux One of the most important criteria for the utilization of this secondary resource is the recovery of iron from the slag matrix to decrease the volume of dumped slag The molten oxidation process with crushing magnetic separation appears to be a more sustainable
·Air cooled copper slag has a black colour and glassy appearance The specific gravity varies with iron content from a low of to as high as The unit weight of copper slag is somewhat higher than that of conventional aggregate The absorption capacity of the material is typically very low %
·This fraction is significant because it affects heavily on the copper recovery during the slag cleaning phase Basically the fraction of oxide copper is dependent on the amount of sulfur present which was kept fixed at % The higher the oxidation degree and thus the copper content in slag the higher the oxidized copper content as a
·The proposed process includes the steps of a crushing waste copper slag; b mixing the waste slag crushed in step a with petroleum coke as a reducing agent and subjecting the mixture to a reduction reaction; c crushing the material resulting from step b ; and d separating the material obtained in step c by dry magnetic separation
·The majority of a copper smelting charge is made up of copper and iron sulphides and oxides; other ingredients include aluminum oxide Al 2 O 3 [17] magnesium oxide MgO calcium oxide CaO and silicon dioxide SiO 2 [18] Since copper slag has pozzolanic properties it has cementitious properties and can be used to substitute cement in some cases
·With the growth of industrialization there has been a gradual increase in demand for mineral resources in China leading to large scale mining and the open accumulation of copper tailings [1 2] Currently most of the copper smelting are either abandoned discarded randomly or merely utilized for backfilling [3] road construction [4] etc resulting in low

·Flotation is one of the most important methods for recovering copper from copper slag However traditional grinding may be over grinding sometimes resulting in smaller interface difference
·Conventionally little chemical adjustments are made to the slag prior to its processing for subsequent use or disposal However recent attempts have looked into modifying the chemical composition of slag while hot to render its chemistry and properties suitable for high value products or recovery of minerals/metals from slag [11 12] Nonetheless the majority of
·Concrete mixtures were made using varying amounts of waste copper slag CS and bottom ash CBA 0 60% in equal proportions as a partial substitute for natural sand as well as fly ash 0 30% as cement Slump unit weight split tensile strength compressive strength and microstructural characteristics such as X ray diffraction SEM
·Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper According to Bond s Third Theory of Comminution the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product
·Copper slag used in this study was the secondary tailings of a copper slag after slow cooling crushing grinding and flotation The main chemical composition of the copper slag is given in Table 2 The main ingredients of the slag are % Fe Total and % SiO 2 the content of copper and harmful element sulfur is low
·Copper slag recycle copper process includes crushing milling flotation dehydration Environmental impact single data of each process stage is total environmental
·The technological factors required to improve the operational properties of granulated metallurgical slags demanded in the building industry have been analyzed In order to satisfy these factors a new technology for hydro vacuum granulation of slag melts HVG has been developed It is shown that the main advantage of the proposed HVG process is the
·The resource utilization of copper slag is an attractive option of iron resource Thermal energy recovery and direct reduction TER DR system was proposed in this study the input temperature of copper slag in Unit 1 Unit 2 and Unit 3 are 1573 K 1373 K and 373 K respectively Carbon bearing pellet is heat at 1373 K in Unit 4 and DRI is
·Commonly Used Mineral Processing Equipment for Copper Slag Crushing Equipment At present it mainly uses jaw crushers The application of other crushing equipment with high efficiency and large crushing ratio such as deep cavity jaw crushers double moving jaw crushers inertial cone crushers etc is also receiving increasing attention
