Taking the flotation process of quartz vein gold ore as the research object, three independent parameters that have an impact on the flotation process are selected as variables, including the fineness, the dosage of xanthate, and the dosage of QX-3 flotation oil. A multi-objective optimization model is constructed with gold

Optimization of flotation variables for the recovery of hematite particles from BHQ ore Swagat S. Rath Hrushikesh Sahoo B. Das 【】： The technology for beneficiation of banded iron ores containing low iron value is a challenging task due to increasing demand of quality iron ore in India.

Higher iron grades were obtained at pH levels between neutral and pH 9. This underlines the importance of the surface charge effect of the ore on its flotation characteristics. The results serve as good baseline conditions for further optimization. IntroductionBeneficiation of iron ore by flotation is widely used in Brazil, India and China.

Optimization of flotation variables for the recovery of hematite particles from BHQ ore. The technology for beneficiation of banded iron ores containing low iron value is a challenging task due to increasing demand of quality iron ore in India.

At pH 7.0, the flotation recoveries of quartz were about 3.12%, 5.7%, 5.13%, 8.75% and 3.6% for NPHA-2, NPHA-4, NPHA-6, NPHA-8 and BHA, respectively, which were much lower than cassiterite under the same conditions. Meanwhile, the flotation behaviors of feldspar were basically similar to quartz.

A new surfactant butane-3-heptyloxy-1,2-diamine [CH3(CH2)6OCH(CH3)CH(NH2)CH2NH2; BHLD] was synthesized. It has been innovatively used as a collector in the flotation of quartz. In this present study, the flotation behaviors of quartz with BHLD were investigated by micro-flotation of quartz. It was found that the recovery of the quartz reaches …

Results obtained from mixed minerals flotation showed that quartz's recovery and grade were ~90% and ~64% when HMLHF was used at pH 11. When THAI was used, the recovery and grade of quartz were 87% and 70.3%, respectively, compared with 87% and 65.3% when commercial amine collector was used"--Abstract, page iii.

The reverse flotation tests were conducted using two types of ionic liquid collectors (THAI and HMLHF) in micro-flotation system wherein pure apatite and quartz were used as an example of phosphate and silicate minerals, respectively. Results obtained from mixed minerals flotation showed that quartz's recovery and grade were ~90% and ~64%

Finally, the multi-objective optimal solution was obtained. In this paper, the multi-objective optimization problem in the flotation process of quartz vein type gold ore was studied, and the optimal combination of various parameters in the flotation process was obtained. This paper carried out flotation experiments for a single type of equipment.

So, the optimization of this process is an important challenge. This study assessed the implementation of a quadratic model and an artificial neural network (ANN) for the optimization of hematite and quartz floatability and recovery. The flotation process was carried out using a biosurfactant extracted from the Rhodococcus erythropolis bacteria ...
