Jun 19, 2019· ferrites gives the zinc slag-containing materials, in which they are present, magnetic properties, but their complex chemical (intermetallic connections) form prevents simple separation of iron compounds from zinc compounds via an external magnetic field. In our work a novel combination of pyro- and hydrometallurgical methods for the treatment
[10], direct reduction-magnetic separation process to recover iron and copper [11] and flocculation-magnetic separation to recover iron as magnetite [12]. Since the content of non-ferrous metals is low compared with iron in the slag, the enrichment of these non-ferrous metal may be enhanced by controlling the reduction of iron,
The samples were characterized after sieve analysis. Magnetic separator is used to separate between magnetic and non-magnetic portion of blank sand. XRF and FTIR were used to know the metal content in black sand. Before magnetic separation black sand contain about 43.2 wt% SiO2, Al 2 O 3 with 21.1 wt% and Fe 2 O 3 with 17.2 wt% and 12.0% TiO2.
A novel method to recover zinc and iron from high iron-bearing zinc calcine by reduction roasting-low acid leaching-magnetic separation was proposed.
Feb 09, 2018· About 10 per cent. of zinc is contained by the calcined iron which may not be separated from it without resort to chemical means. To enrich still further some of the calcined products single separators are employed, as is also a high-intensity separator. At Mercadel, Santander, Spain, there is a magnetic-separation plant treating oxidized zinc ...
decomposition of fayaltie into metallic iron and free silica, whereas zinc and lead are enriched in dust. Previous studies on carbothermic reduction focused on the phase transformation of iron, copper, and zinc in CS for iron recovery by magnetic separation, and few studies discussed the phase transformation of silica [3, 9, 11].
Ores which contains some magnetic particles or they can attract by the magnetic field only they can be concentrated by magnetic separation method.
