In this work, the impact of water type on borate ore flotation was investigated, while various physical parameters during flotation were considered in order to compare the results. Two different colemanite samples from Emet deposits of Turkey, named as Emet-A and Emet-B contained 44% B 2 O 3 and 40% B 2 O 3, respectively.
The flotation beneficiation of phosphate ore is increasingly facing challenges, especially for finely disseminated sedimentary ores rich in carbonates. This study aims to optimize and assess the impact of key hydrodynamic parameters including pulp density, air flowrate and impeller speed on flotation and metallurgical responses …

traditional mechanical flotation cell. The data indicate that exposed grain surface area is a critical factor for coarse particle flotation. For the gold-bearing sulfide ore examined in this study, the HRXMT data suggest that near complete recoveries of coarse (850x500 m) multiphase particles containing as little as 1%
The present work investigates a comparative study between mechanical and ImhoflotTM cells on a mini-pilot scale and the applicability of one self-aspirated H-16 cell (hybrid ImhoflotTM cell) on an industrial scale on-site. The VM-04 cell (vertical feed to the separator vessel with 400 mm diameter) was fabricated, developed, and examined. The …
The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (C-matter). In this study, the effect of MIBC on C-matter flotation was investigated to …
Gold Flotation Column. The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was …
This type of ore is generally processed by flotation, which concentrates the gold in the non-ferrous ore concentrate and then recovers the gold during the smelting process. Gold can be obtained by cyanidation from gold-bearing concentrates produced by the flotation of sulfide minerals in mines.
The nature of the particles within the flash cell will be examined, as will the impact on the type of particles that are passed to downstream processes when the flash flotation cell is taken off-line. The development of a laboratory method to determine whether an ore is suitable to undergo the flash flotation process is also presented for its ...
Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con- ventional cells; (ii) energy-intensive pneumatic cells; (iii) column …
The first part of the study focused on assaying the impact of clays on gold flotation by conducting desliming tests prior to flotation. It was observed that when a large portion of the fines (<10 µm) was removed through desliming, the gold grade in the concentrate increased by a factor of 9.
A high-clay-content gold ore and a clean gold ore with a low clay content were supplied by a gold flotation plant. The key mineral and elemental compositions of the two ores are listed in Tables 1 and 2, respectively.The analysis by quantitative X-ray Diffraction (XRD) indicates that the major gangue minerals in the high-clay-content ore …
