  Slime coatings in froth flotation: A review - ScienceDirect

  2017121 · Slime coating is a significant phenomenon in froth flotation. The adverse effects of slime coating, by which a value mineral is covered by slimes and prevented from direct contact with collectors and/or air bubbles, have been recognized for decades. It happens ubiquitously in the flotation of various minerals, including sulfide minerals …

  Improving Nickel Recovery in Froth Flotation by …

  202141 · This study aims to optimize the traditional flotation process of Mo–Bi sulfide ore by using the difference in natural floatability of minerals for cleaner production. Single-mineral flotation tests demonstrate that the natural floatability of the sulfide minerals investigated decreased in the following order: molybdenite > bismuthinite > pyrite.

  Improved flotation separation of sulfide minerals by …

  2022915 · In a froth flotation cell, the target mineral particles treated by the surfactant named collector will become hydrophobic and attach themselves to the rising air bubble to form particle-rich froth on the suspension surface, while the hydrophilic unwanted gangue minerals are depressed and settled to the bottom of the cell [3].

  Prediction of multi-stage froth flotation efficiency of …

  202451 · Despite the long history of flotation in the mineral processing industry, its prediction and understanding remains a great challenge owing to its many variables acting in a complex manner. In this study, we introduced machine learning (ML) models to predict the grade and yield of a multi-stage flotation process of a complex lead–zinc sulfide ore.

  Fundamentals and Applications of Green Modifiers for Froth Flotation ...

  202216 · Low-cost and environment-friendly green froth flotation modifiers of plant origin, such as guar gum, carboxymethyl cellulose (CMC), and starch, have been used in flotation of some sulfide and non-sulfide minerals. Certain green modifiers may be used as dispersants, flocculants, depressants, or activators. The functions of green modifiers in …

  The effects of mixtures of potassium amyl xanthate (PAX) and …

  2017121 · With deteriorating nickel sulfide ores, more selective collectors and collector mixtures are desired for the efficient extraction of nickel. Thionocarbamates (TC) are another group of thiol collectors used for selective froth flotation of sulfide minerals.

  The effects of saline water on the recovery of lead and zinc sulfide ...

  2023111 · Abstract In this study, we investigated the effects of water salinity on the flotation performance of pure lead and zinc sulfide mineral samples as well as a Pb/Zn complex sulfide ore by means of micro-flotation and batch flotation experiments. Our results showed higher PbS and ZnS recoveries in more concentrated NaCl salt solutions.

  Froth Flotation Process - 911 Metallurgist

  2021120 · Froth Flotation Process. The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use …
