  • Combination Crusher

    Combination Crusher

    The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line. This series of crusher is a new product based on our company's PEL vertical compound crusher and optimized with domestic and foreign fine crushing technology. Its performance has reached the domestic advanced level. It is mainly for all kinds of ore with compressive strength not exceeding 200MPa and water content less than 15%.

On this basis, a review of a number of methods for recovery of metals from the slags was made. It can be seen that a large amount of slags is produced each year. They usually contain a quantity of valuable metals except for blast furnace slag and they are actually a secondary resource of metals. By applying mineral processing technologies, such

recovery of iron from copper flash smelting slags

recovery of iron from copper flash smelting slags

Iron recovery, defined as the ratio of the amount of iron clearly transferred to the base metal ingot to the initial amount of iron in the slag phase before reduction, was maximal (about 90 pct

recoveryofironfrom copperslagusing coal-based direct

The Fe3O4 and Fe2SiO4 in copper slag were successfully reduced to metallic iron by coal-based direct reduction. Under the best reduction conditions of 1300 °C reduction temperature, 30 min reduction time, 35 wt.% coal dosage, and 20 wt.% CaO dosage (0.75 binary basicity), the Fe grade of obtained iron concentration achieved 91.55%, and the Fe recovery was 98.13%

effect of cao addition oniron recoveryfrom copper

We investigated the effect of flux (lime) addition on the reduction behavior of iron oxide in copper slag by solid carbon at 1773 K (1500 °C). In particular, we quantified the recovery of iron by performing typical kinetic analysis and considering slag foaming, which is strongly affected by the thermophysical properties of slags. The iron oxide in the copper slag was consistently reduced by
