Oleate flotation characteristics of hematite have been investigated in thjs study under a wide range of experimental conditions of pH, temperature, ionic strength and collector concentration. The study revealed the following major features of this system which include: (a) a maximum in floatability in the neutral pH range; (b) an increase in the flotation response of hematite with increase eith...

Industrial wastewater contains a lot of pollutants and therefore needs special treatment processes. The treatment process may contain mechanical, biological, chemical, physical and physiochemical such as Coagulation – Flocculation process. The goal of this experimental work was to investigate the effects of coagulationflocculation and dissolved air flotation as a hybrid process of industrial wa...

Froth floatation is an important process used in the mining industry for separating minerals from each other. The separation process is based on rendering a selected mineral hydrophobic using an appropriate hydrophobizing reagent (collector), so that it can selectively attach onto the surfaces of a rising stream of air bubbles. Thus, controlling the hydrophobicity of the minerals to be separate...

Soil transmitted helminths are parasitic groups of worms that live in countries with subtropical or tropical climates. In humans, when exposed to eggs larvae, they can cause infection. Stool examination is divided into qualitative and quantitative examination. Qualitative direct examination, flotation, tape, deposition, thick preparations. Kato-Katz Stoll quantitative. The purpose this study wa...
