Preconcentration strategies in the processing of nickel

Aug 01, 2015 Patents by Petrovich, 1975a, Petrovich, 1975b suggested the use of iminophenols and phenolaldimines as collectors for garnierite (nickel silicate) using small scale laboratory tests. Flotation results indicated concentrate grades of 13.6% Ni at 89.4% Ni recovery using cresyaldiminooctanol and 10.4% Ni grade at 94.2% Ni recovery using methylimino-di-hydroxybenzoic acid

Jun 08, 2016 The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success

flotation technology. the froth flotation process is used to sepa- rate coal and mineral mixtures with particles showing different physico-chemical surface properties towards water. these properties are either natural or can be produced and even enhanced by treatment with surface- active reagents. Basically, the flotation process itself takes place when mineral particles attach to air bub- bles and rise up. since the beginning of the 20th century froth flotation

How to Prepare Flotation Reagent?

Mar 25, 2019 For a flotation reagent with a small dosage, if the concentration is too large, it would be difficult to properly control the dosage of it, and the transportation would be inconvenient too. When preparing an aqueous solution, we often dissolve the flotation reagent in the container with a small amount of water
