Studies on the Beneficiation of Barite
Flotation tests were conducted using ionic and anionic collectors and the results are presented in Tables 2-4. In the presence of ionic collectors i.e Armoflote-17 and Liquid B-50 most of the silica and sili e minerals were floated in preference to barite reverse flotation . However barite alone was
The anionic flotation of fluorite from barite using
The anionic reagents have been used in the flotation separation of fluorite from barite such as sodium oleate NaOl and sodium petroleum sulfonate SPS 89 . These anionic collectors are non-selectivity for the fluorite and barite 10 thereby they need to be used with the depressant to inhibit the flotation of barite.

Eight Factors Affecting the Flotation Process-prm
Reagent dosage: In the flotation process the pulp must maintain a certain concentration of agents to obtain good flotation technology indi ors. When the pulp is relatively thick the concentration of reagents in the liquid phase increases and the dosage of reagents for each ton of ore will be reduced.
These aspects influencing flotation cell effect should not be
Therefore in the flotation process only suitable air inflation can acquire the ideal flotation effect. Four. The influence of reagent system . The flotation reagent system mainly includes the adding method and reagent amount. The suitable reagent system is the guarantee of the quality of flotation concentration product.
