Process for extracting molybdenum from wulfenite ore ...

When caustic soda is used, a suitable amount is about 2.5 times the weight of the molybdenum present in the ore. A preferred method of employing the latter reagent is to dissolve it in the least amount of water required to moisten the ore uniformly, when thoroughly mixed therewith.

Rapid high-performance sample ... - sciencedirect

It should be noted, that although the molybdenum ore was sulfidic in nature, it fell under the high-boiling acid treatment because it used sulfuric acid and nitric acid for its dissolution. Although reverse aqua regia is generally effective for the oxidation of sulfide to sulfur, it was not adequate for the recovery of molybdenum in this sample.

Stoping Mining Methods - Metallurgist & Mineral Processing ...

Cut-and-fill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy. The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or masses.
