The dosages of SETX used for the flotation was found to be generally higher than that of sodium iso-propyl xanthate (SIPX) used for another copper ore of non-carbonatitic origin. However, the successful flotation of the ore ground coarser than the conventional practice of 80% passing 75 µm is economically significant in view of the …

With other ores the selection is nil or wholly inefficient. It may be put down as an axiom of the art that no one substance is universally applicable as an "oil" in froth-flotation concentration of all ores. Grind …

In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. Mining companies are investing in advanced sensors, data integration, and machine learning to gain deeper insights into …

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 …

Starch and meta bisulphite were used as a depressant for pure pyrite sample and a pyritic copper ore at two different pHs values. pH was 6.5 and 10 in pure pyrite study while it was 6.9 and 12 in ...

About 3.6 kg of the ore mixture ground 55% passing 75 µm was weighed into a 8 litre Denver cell and mixed with water to obtain a pulp relative density of 1.29. The pulp was dosed with 180 g/t ...

The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of …

A copper–molybdenum iso-flotability flotation process has been developed to efficiently improve the recovery of molybdenite from Duobaoshan porphyry Cu–Mo ores. The effects of flotation ...

Fig. 1 shows the circuit in which a copper ore feed is upgraded first in a rougher bank, consisting of five mechanically agitated flotation cells, each with a …

A mineralogical prediction model was proposed to estimate the flotation behavior of blended Cu–Mo ore as a function of the flotation behavior of each Cu–Mo ore. The flotation results show that the …

where r is the measured cumulative recovery of either valuable or gangue at time t, R is the calculated equilibrium recovery as t → ∞, and K is a first-order rate constant of mass removal (units of time −1) that describes the shape of the time–recovery curve at small flotation times.Thus, each time-recovery profile can be characterized by two …

The aim of this study is to apply process mineralogy as a practical tool for further understanding and predicting the flotation kinetics of the copper sulfide minerals. The minerals' composition and association, grain distribution, and liberation within the ore samples were analyzed in the feed, concentrate, and the tailings of the flotation …

A basic rougher-scavenger flotation procedure, identical to the one described in Tijsseling et al. (2020), was designed to investigate the flotation characteristics.An overview of the flotation procedure can be found in Table 1.Both rougher and scavenger flotation stages were operated under identical conditions, in the same one-litre Denver D12 flotation …

More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal.

The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world.

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …

Moreover, enrichment of fine particles formed by virtue of low grade ores is another obstacle that makes flotation cell design and manufacturing, much more important. Flotation cell performance improvements only comes handy by being supported by better communication at all levels between mines, equipment manufacturers and chemical …

Role of starch and metabisulphite on pure pyrite and pyritic copper ore flotation 43 occurred with 1.7 mg/ dm3, while 21% depression occurred with the same dosages of starch at pH 6.5 where pyrite ...

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is …

The beneficiation processes of porphyry copper–molybdenum ores include mixed, preferential, and iso–flotability flotation process. Because of its mature technology and good indicators, mixed flotation is widely used for the treatment of copper-molybdenum ores. However, research on the remaining two processes is still ongoing.

To model the copper ore flotation process, an analysis was made on the factors that affect the results of the process. We choose the following seven factors as independent variables. ...

The efficiency of a flotation circuit operation relies on several factors that are pertinent to mineral nature and structure (variability of ore feed, particle size, …

Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be increased in copper ores, so the appropriate depression of sphalerite floatability should be achieved to obtain saleable copper …
