The interaction of two clay minerals, kaolinite and bentonite with gypsum and its effects on the flotation of a copper–gold ore was investigated in this study. It was found that bentonite increased the viscosity more than kaolinite when mixed with the copper–gold ore at low shear rates.
gypsum flotation test Construction Waste Crusher Construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
The effect of the parameters such as pH, pulp density, particle size and collector amount were investigated. KAX was used as collector and Dow-250 was used as frother. Key Words: Sulfurization, flotation, copper, gold, silver 1. INTRODUCTION Flotation has been utilized in the mineral processing industry to concentrate base

evaluated the effect of three chemical reagent configuration on selective flotation in low and high pyritic copper sulphide ores. They showed that the collector of isopropyl-n-ethyl thionocarbamate creates the highest copper grade and the lowest iron recovery (Hassanzadeh and Hasanzadeh, 2016).
This paper aims to understand the fundamental interaction mechanism between molybdenite and kaolinite in gypsum solution using kerosene as collector. Micro-flotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral. The results showed that the recovery of molybdenite decreased from 86% to 74% ...
The interaction of two clay minerals, kaolinite and bentonite with gypsum and its effects on the flotation of a copper–gold ore was investigated in this study. It was found that bentonite increased the viscosity more than kaolinite when mixed with the copper–gold ore at low shear rates.
Jun 01, 2015· Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.
A detailed study was conducted to evaluate the effect of particle size, pH, flotation time, collector type and addition on efficiency of tennantite flotation. It was shown that maximum copper recovery of 95,3% was obtained at pH 12.3 by lime.It was suggested to grind up to 65.72% of -0.074 mm to achieve the optimum recovery of copper and high

optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore. The parameters investigated include collector dosage, percentage solids, depressant dosage and pH. The effects of these parameters at three different levels on the recovery of Ni, Cu and Co were investigated using an L 9 Taguchi orthogonal array.
The interaction of two clay minerals, kaolinite and bentonite with gypsum and its effects on the flotation of a copper–gold ore was investigated in this study. It was found that bentonite increased the viscosity more than kaolinite when mixed with the copper–gold ore at low shear rates.
The present work initially studies the kinetics of microwave-assisted grinding and flotation in a porphyry copper deposit. The kinetics tests were carried out on the untreated and microwave irradiated samples by varying the exposure time from 15-150 sec. Optical microscopy, energy-dispersive X-ray spectroscopy and scanning electron microscopy were used for determining the mineral liberation ...
Water in flotation circuits is used for transporting solids and is a critical part in the processing of minerals [4], therefore, understanding its effects on flotation is critical. However, mill personnel do not often have sufficient understanding of the effects of recycled water on flotation and do not have the time and resources to carry out ...
In this paper, the influence of Ca2+ on the flotation of a skarn type molybdenum ore and pure molybdenite mineral at pH 8 was studied using diesel as the collector. It was found that Ca2+ had little effect on molybdenum flotation at low concentrations. By further increasing Ca2+ concentration, the floatability of molybdenite—especially from the fine size fractions—was depressed even ...
This paper presents the sulfidisation promotion effect of ammonium sulfate on the sulfidisation flotation of both malachite and copper oxide ores. Copper oxide ores are commonly difficult-to-float due to its molecular structure, and adding sodium sulfide as activator is necessary; however, its dosage to the flotation pulp must be strictly controlled, as it is also a powerful depressant for ...

Micro-flotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral.
In concentration by flotation, the soluble components of an ore may play an important role. Occasionally ores that are shown by preliminary test to be unsuitable for flotation may be treated by the process after the soluble ingredients have been removed by decantation. On the other hand, excellent results may be obtained on certain ores by flotation in fresh water; but when the water is fouled ...
