Figure 9.2 shows a permanent magnetic drum separator, which consists mainly of a permanent magnet system, a rotating drum, a separating chute, a feed tank, and a flushing pipe. For magnetite separation, the magnetic field intensity on the surface of the drum is between 0.1 and 0.4 T.However, for other applications, the intensity may reach as high as 0.8 T.

May 3, 2022G. sulfurreducens was used to reduce synthetic Co-ferrihydrite as an analogue of natural cobalt-iron-oxides. Magnetite [Fe(II)/Fe(III)3O4] production was confirmed by powder X-ray diffraction (XRD), SXM and X-ray magnetic circular dichroism (XMCD) data, where best fits of the latter suggested Co-bearing magnetite.

Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
