Manganese Silver Ore Treatment Method
The ore, mainly quartz, carried 18 per cent manganese dioxide, 30 oz. silver, and 8 dwt. gold. After being crushed to 1 in., it was heated 4 hr. in a rotary kiln. It remained 1½ hr. in the reducing section of the lain in producer gas at 600°C. The MnO2 was reduced to 2 per cent. ... Silver ores with sulfide manganese. (Suitable for flotation).

Studies on the influence of a flotation collector reagent on iron ore
The properties of iron ore green pellets with varying additions of a surface-active flotation collector reagent (Atrac) were studied by small-scale balling. The compression strength and plasticity were measured with a semi-automatic measuring device and the pressure curves were saved and subjected to further mathematical treatment. …

Cobalt Extraction Mechanisms | SpringerLink
For cobalt associated with sulfides, the flotation process is easier since Co floats easily together with copper sulfides using xanthate-type collectors. Here, a single sulfide concentrate or a copper-rich and cobalt-rich concentrate can be produced. For the latter, a differential flotation is carried out as follows : 1.

2.1.9. Manganese. The addition of manganese (Mn) to magnesium is reduced due to its low solubility (2.2 wt.%) in magnesium. But adding Mn as a binary element in the alloys of Mg (up to 5 wt.%), exhibited no significant change in the rate of corrosion. Hence manganese is used along with other alloys like aluminum.
