ABSTRACT Gravity separation jigging and flotation were used to upgrade barite ore from the under developed Mehdi Abad deposit with general specific gravity gr/cm3 Jigging experiments on coarse particles did not indicate significant upgrading gr/cm3 and recovery 90% where barite particles are mainly liberated in fine size fractions 175µm
·Barite Flotation Separation Process If barite ore contains a high barium sulfate BaSO4 content it is associated with gangue minerals such as quartz calcite and fluorite Flotation machine is often required to separate the valuable barite from other minerals present in the ore The flotation process involves adding reagents to create froth
·During fluorite flotation the separation efficiency of fluorite from barite and calcite was low owing to their similar surface properties therefore developing highly selective flotation
on barite concentration by flotation This study primarily aimed to obtain a barite concentrate with a minimum 90% BaSO 4 requirement of the market by concentrating on a barite tailing by flotation For this purpose first laboratory scale flotation tests were carried out to determine the effects of some operating parameters on the rougher

·As a non metallic mineral fluorite is commonly appeared in industrial processes related to fluorine It is often found with the emergence of other calcium and silicate minerals such as quartz barite and small amounts of pyrite [1 2] The flotation for the separation and purification of fluorite from these associated minerals is based on the differences in surface properties
·Barite powder as a weighting agent is the most important additive into drilling mud for the oil and gas extraction In this study production of brown barite powder SG g/cm³ was examined
·Barite and fluorite have similar physical and chemical properties and floatability and traditional flotation reagents are difficult to effectively separate these two minerals In order to realize the effective separation of the two minerals a new system with high selectivity and strong collecting ability α BLA bromododecanoic acid system was selected in this paper
Fluorite barite and calcite are important industry minerals However they often co exist presenting difficulty in selectively separating them due to their similar surface properties In this study valonea extract and sodium fluosilicate were used as depressants to selectively separate them by flotation with sodium oleate as the collector The single mineral flotation results
·Barite was recovered up to 87% at pH = 3 in sole mineral flotation experiments and flotation of the mixed sample also proved a successful selective separation of barite 76% recovery from
·The flotation experiments showed that under the SDS flotation system when the pH was and the amount of depressant β CD was 900 g/t the barite recovery and density reached the highest values
·It indicates that for the barite fluorite bulk flotation and then separation process 1 the recovery and grade of barite in its concentrates reached ∼ % and % and those of fluorite in its concentrates were of ∼ % and % respectively Therefore the adhesion force was feasible as the criterion to design and develop
·Therefore the barite inhibitor is mainly used in the flotation of barite fluorite type ore to inhabit barite Barite inhibitors mainly include polymeric carbohydrates such as tannin extract starch dextrin and sodium lignosulfonate and inorganic salt compounds composed of sodium silicate sodium carbonate sodium hexametaphosphate Al 3 and
·The effects of ultrasonic waves on the flotation of calcite barite and quartz have been investigated in the case of single and mixed minerals In the case of single minerals ultrasonic treatment has a positive effect in the flotation performance of calcite and barite while showing a negative effect in the case of quartz Similar results were obtained in the case of
