  Lime use and functionality in sulphide mineral flotation: A …

  2019111 · Primary grinding – Lime is often added into the semi-autogenous (SAG) mill together with the ore feed and process water. Sulfide minerals are, by nature, acid to varying degrees causing the milled pulp to have a pH ranging from 4 to 8 depending on the sulphide and gangue mineral composition of the ore.

  Should the slurry density in a grinding mill be adjusted as a …

  200771 · The effect of slurry density on grinding has been frequently studied in terms of rheological properties (Napier-Munn et al., 1996, Klimpel, 1997, Bazin and Boudrias-Chapleau, 2005) but an unambiguous conclusion on the effect of that variable is still lacking. Slurry density influences the ore transportation through the grinding mill (Laplante and …

  Influence of Surfactant for Stabilization and Pipeline …

  2022812 · Iron ore is generally transported using a traditional method that releases significant amounts of dust into the environment. In contrast, the pipeline transportation of slurry is noticeably a sustainable approach for efficiently transporting iron ore by reducing the environmental pollution. The interparticle interaction of the iron ore particles should be …

  Interactive effect of minerals on complex ore flotation: A …

  2020512 · Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation …

  Effects of slurry pool volume on milling efficiency

  201441 · The effects of slurry pooling on ball milling have been investigated. Product fineness was found not to be a function of slurry pool volume. High ball filling J and slurry filling 1.0 ≤ U < 1.3 led to high production of fines. From a batch milling perspective, slurry pool is undesirable for effective grinding.

  Effect of corrosion inhibitors on grinding and flotation of a lead-zinc ore

  199381 · Grinding and flotation experiments on a Pb-Zn ore were carried out to evaluate: 1) wear of the grinding media both in the presence and absence of an inhibitor and 2) effect of the inhibitor on the flotation of Pb Zn minerals. The percentage reduction in the wear of the grinding media was observed to be between 25–36%, depending on the type …

  Effect of mill speed and slurry filling on the charge dynamics …

  201981 · The laboratory ball mill was lined with 12 pieces of trapezium lifters and filled with Jb = 25% grinding balls. An iron ore was used to prepare the slurry at 50% solid concentration by mass. A series of tests were carried out to investigate the charge dynamics at different mill speeds and slurry filling.
