Removal of Sulfate Ions by Precipitation and Flotation

Mario Santander

The removal of sulfate ions from natural waters, as well as from industrial effluents of different origins, is a problem, considering that most of the proposed processes are inefficient and have a high cost, mainly when reducing the sulfate ion concentration to values below 500 mg.L−1 is required. The flotation technique, combined with precipitation, has proven to be efficient for the removal of heavy metal ions. However, there is not enough research to confirm its efficiency for the removal of sulfate ions. This article presents the results of sulfate ion removal from synthetic solutions prepared in an acidic medium, applying the co-precipitation techniques with polyaluminum chloride (PAC) and solid/liquid separation by dissolved air flotation (DAF). The effect of the pH, the [PAC: sulfate ions] ratio, the effect of saturated water flow with air, and the flocculant and collector doses were studied. The achieved results confirm that it is possible to reduce the concentration of sulf...

Evaluation of electrocoagulation process for the removal of strontium and cesium from aqueous solution

2014 •

Subramanyan Vasudevan

ABSTRACT The present research work deals with an evaluation of electrocoagulation process for the removal of radioactive contaminants like strontium and cesium from water using different anode materials like aluminum, iron, magnesium, and zinc with galvanized iron as cathode. The optimization of various operating parameters like effect of pH, current density, temperature, and inter-electrode distance on the removal efficiency of strontium and cesium were carried out. The results showed that the maximum removal efficiency of 97.0% and 96.8% was achieved for strontium and cesium respectively with magnesium as anode at a current density of 0.08 A/dm2 and pH of 7.0. First and second-order rate equations were applied to study adsorption kinetics. The adsorption process follows second order kinetics model with good correlation. Langmuir and Freundlich adsorption isotherm model were studied using experimental data. The Langmuir adsorption isotherm favors monolayer coverage of adsorbed molecules for adsorption of strontium and cesium. Temperature studies showed that adsorption was endothermic and spontaneous in nature.

Effect of Ether Mono Amine Collector on the Cationic Flotation of Micaceous Minerals—A Comparative Study

Hossein Mohammadi-Manesh

Micaceous minerals, known as layer silicates, are counted mostly as the gangue minerals associated with valuable minerals, especially iron oxides. They mainly reject through the reverse flotation process using the cationic collectors, e.g., ether amines, to improve process sustainability. Although ether amines have been applied for floating the wide range of silicates, few investigations explored their adsorption behaviors on the micaceous minerals. In this study, flotation of phlogopite, biotite, and quartz (for comparison purposes) in the presence of Flotigam®EDA (EDA) (commercial ether monoamine collector), at pH 10 was investigated through the single mineral micro–flotation experiments. Adsorption behaviors were explored by the contact angle, residual surface tension measurements, and zeta potential analyses. Micro–flotation outcomes indicated that the quartz floatability was more than phlogopite and biotite. In the presence of 30 mg/dm3 EDA, their recoveries were 97.1, 46.3, an...

Sulphate Removal from Flotation Process Water Using Ion-Exchange Resin Column System

Zafir Ekmekçi

Water chemistry is one of the most important parameters affecting flotation performance. Various types of ions can dissolve and accumulate in process water depending on ore mineralogy, reagent scheme, grinding medium and chemistry of mine site water. Sulfur-based ions (sulfate, thiosulfate, polythionate) are generally observed in flotation of sulfide ores. High concentrations of these ions may reduce efficiency of the flotation process, causing scale problems. Removal of these ions from process water often requires complex water treatment plants with high capital and operating costs. In this study, partial cleaning of water was investigated as an alternative approach for decreasing high sulphate concentrations of 3000–3800 mg/L down to 1000–1500 mg/L, an acceptable concentration for most sulfide ore flotation plants, by using an ion-exchange resin. For this purpose, detailed adsorption tests were performed using a laboratory-scale column system to determine the most suitable type of...

What is a mineral in chemistry? ›

Minerals Definition

Mineral is a naturally occurring inorganic solid with a definite chemical composition and a crystalline structure. The earth is composed of mineral elements, either alone or in a myriad of combinations called compounds. A mineral is composed of a single element or compound.

What is the chemical analysis of minerals? ›

A chemical analysis of a mineral is expressed as a table of weight percent (wt. %) of its component elements or oxides. Concentrations lower than about 0.5 wt. % are often expressed as parts per million (ppm) by weight of element.

What is an example of minerals? ›

Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium.

What are the limitations of mineral processing? ›

The limitation of the technique is for the minerals whose volume percentage is less than 3% in the sample. Some of the trace phases of very small size can not be studied by optical microscopy or XRD.

What is the greatest challenge regarding mineral resources? ›

Reducing energy consumption and breaking the current link between metal production and greenhouse gas emissions are among the greatest challenges to secure a sustainable mineral supply.

What are the 5 requirements for a mineral? ›

The term “minerals” as used in nutrition labels and pharmaceutical products is not the same as a mineral in a geological sense. In geology, the classic definition of a mineral is: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) defined chemical composition.

How does mineral chemistry affect mineral properties? ›

Elements with similar properties may substitute for each other in minerals and many minerals have variable compositions. Ionic, covalent, or metallic bonding are most common in minerals. The kind of bonding affects mineral properties.
