Cobalt Kunai

The Cobalt Kunai is a craftable Hardmode dagger.When used, it throws a cobalt dagger that pierces twice and travels a moderate distance before being affected by gravity. Performing a stealth strike with a Cobalt Kunai will instead fire three non-piercing cobalt energy bolts that home in on nearby enemies, ignore gravity and deal 185% of the …

Continuous gravity concentration in Gold grinding circuits …

The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

Cobalt Flotation Recovery

The major cobalt source in the ore is the mineral siegenite. Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore. The siegenite is often present as an intimate replacement intergrowth with chalcopyrite (fig. 1), sphalerite, galena (fig. 2), and the iron sulfides, pyrite and marcasite.
