iron ore flotation water quality

The impact of water quality on flotation performance

Water represents 80–85% of the volume of mineral pulp processed in flotation circuits. Imperatives for a more detailed focus on circuit water quality and its control have come from increasing requirements to use relatively impure primary water supplies (e.g. high

A review of the effect of water quality on flotation ...

01/11/2013  Currently, water quality problems in flotation are generally dealt with by internal solutions that focus on the flotation operation itself more or less haphazardly, that is, without a diagnostic and proactive understanding of the causes for water quality variation. This may lead to a constrained view of opportunities to deal with the problems and thus hinders the ongoing implementation of good water

The effect of water quality on flotation - Froth Flotation ...

In this paper, a review of the existing studies on water quality variation in flotation is given in three aspects: causes of water quality variation, consequences of water quality variation and solutions for problems caused by water quality variation. Based on the three aspects, a framework was developed, with which these studies were categorized and structured. Organizing literature in this way makes it

THE INFLUENCE OF WATER QUALITY ON THE FLOTATION OF THE ...

The effect of recycling the water used for flotation on the water quality is summarised in figure 6. The results are rather disappointing in the sense that the hydrolysis of most of the metal cations at pH 9.18 caused their concentrations to be generally below the detection limit of typically 0.02 mg/L. This is unfortunate as a cation like the cuprous ion will certainly be capable of ...

Abstract: It is well known that reverse flotation performance of iron oxides is affected by water quality. Since many potential variations among water sources recycling in a mineral processing plant bring unpredictable effects on the flotation system of iron oxides: disturbing ions/compounds, pH, hardness, residual reagents, etc. In this study, the recycled tailing water from a local plant,

The Effects of Iron in Water on Aquatic Life Cuteness

Iron (Fe) occurs naturally in water at a rate of roughly 1-3 parts per billion (ppb) in ocean water, about 1 part per million (ppm) in river water and 100ppm in groundwater. Iron comes from various minerals in the soil, which is why groundwater contains the highest iron concentrations. Iron levels in water vary depending on several factors and can affect aquatic populations, behavior and health.

For Brazilian iron ore producers, reverse cationic flotation is preferred to obtain high quality concentrates from silicate ores. The SiO2 (silica) particles are rendered hydrophobic by amine (cationic collector) in alkaline conditions, while iron is depressed by the addition of starch. The injected air forms bubbles to which the silica attaches due to the amine action, leaving iron rich ...
