As shown in Fig. 2, the flotation recoveries of barite and fluorite were very high with NaOl alone, indicating the poor selectivity between fluorite and barite in the absence of GS.With the addition of 75 mg/L GS prior to NaOl, the flotation behavior of fluorite was not affected at pH 6.0-8.0 but slightly decreased to a certain extent at pH > 8.0.Barite, a weighting agent in the drilling muds, is one of them. In order to answer the requirements of the oil industry, the barite ores have to be …

Influence of Air Flow Rate and Immersion Depth of Designed Flotation - Beneficiation of Barite Dumps by Flotation Column; Lab
Flotation tests were conducted using cationic and anionic collectors and the results are presented in Tables 2-4. In the presence of cationic collectors i.e Armoflote-17 and Liquid B-50, most of the silica and silicate minerals were floated in preference to barite (reverse flotation). However barite alone wasThe flotation results showed that SPS performed well in a wide pH region (7–11) even at a low temperature (5 °C), while the flotability of fluorite and barite were almost the same.

Among them, the beneficiation of barite ore associated with sulfide ore usually adopts flotation method or combined gravity separation and flotation process to recover barite after removing sulfide ore. 1. Barite hand selection method. After the raw ore is mined, simple manual selection is a common beneficiation method for many small mines.In order to improve the flotation separation efficiency of bastnaesite from barite and calcite, a novel collector, octylamino-bis-(butanohydroxamic acid) (OBHA), with large molecular structure and two functional groups was synthesized based on the molecular design of flotation reagents theory.OBHA was adopted as collector in both single, mixed binary and …
