MINeRAL PROCeSSING. Meschac-Bill Kime Arthur Kaniki. Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals. The shortest interval provided data more closely related to the breakage …
Mineral Processing and Extractive Metallurgy Review ... Therefore, a systematic work has been done to evaluate the compressive strength of briquettes composed of manganese oxidized ore fines, ferromanganese dust, charcoal fines, and three different binders, bentonite, pregelatinized starch, and slaked lime + molasses. ...
Separation flotation method can also achieve good results for refractory oxidized copper ore. It is to crush the mineral to a certain particle size, mix 0.1% ~ 1.0% salt and 0.5% ~ 2.0% pulverized coal, and heat it to about 900 ℃ in oxygen isolation. The copper in the ore will precipitate on the carbon particle surface in metal state.
The ore used in this study originated from the Central African Copper Belt region and contained very high levels of well-oxidized copper (2–8%) and cobalt (1–4%) minerals.
Oxidized gold ore is a common type of ore in gold deposits. It is characterized by the presence of gold in the form of oxides and symbiosis with sulfides. Due to its special mineral composition and…

The plagioclase content of this ore is also particularly low (4.4%) compared to other Merensky ores (e.g. Solomon et al., 2011; Vogeli et al., 2011), but this may well be due to the mining cut and the processing of ''silicate reef'' compared to pure Merensky reef rather than the effect of oxidation.
