Effect of carbonate alkalinity on flotation behavior of quartz

Alkalinity is defined as the capacity of a water to neutralize strong acids. In natural waters, this capacity is generally attributable to bases such as HCO3-, CO32 and OH- as well as to species often present in small concentrations such as silicates, borates, ammonia, phosphates and organic bases. Carbonate alkalinity of process waters in mineral processing may change as a result of the seasonal climatic changes, the fresh water source and the amount of recycled process water. Any mineral processing plants in general and flotation plants in particular will have process waters with different alkalinities. Therefore, carbonate alkalinity should be of concern in flotation.

The effects of phenols on hydrochloric acid leaching of metal oxides is investigated theoretically. A mathematical model is developed for the early stages of leaching assuming that steady state conditions and Fick's first law are valid for the formation and diffusion of metal cations through the Helmholtz-Stern interface. It is found theoretically that the leaching rate is exponentially proportional to acid and phenol concentrations and any metal-phenol complex which can be decomposed by chloride ions shoul...
Effect of particle size on heat of hydration of pozzolan incorporated cements /
Ardoğa, Mehmet Kemal; Tokyay, Mustafa; Erdoğan, Sinan Turhan; Department of Civil Engineering (2014)
Hydration reactions, the chemical reactions between cement and water are exothermic. The determination of the heat of hydration and rate of heat evolution of cement are extremely important to understand the hydration mechanism. In this study, clinker and gypsum rock were ground after adding natural pozzolan (trass) with various proportions until a specific fineness value and different cements were obtained. These cements were divided into particle size groups with a sonic sifter and the heat of hydration an...
Effect of heat treatment on grindabilities of celestite and gypsum and separation of heated mixture by differential grinding
Sener, S; Bilgen, S; Ozbayoglu, G (Elsevier BV, 2004-03-01)
This study was conducted to determine thermal decomposition of gypsum (CaSO4 . 2H(2)O) and celestite (SrSO4), to examine the effect of heating on grindability and the possibility of celestite-gypsum separation by differential grinding after heating. The results indicated that no significant decomposition reaction was observed in celestite up to 900 degreesC whereas the decomposition of gypsum occurred within 100-450 degreesC.
The effects of feed size distribution on confined-bed comminution of quartz and calcite in piston-die press
Hoşten, Çetin; Cimilli, H. (Elsevier BV, 2009-05-16)
Packing characteristics of particle beds, determined mainly by the particle size distribution, exert a critical influence on the interparticle breakage of minerals in confined beds under compression. This paper is concerned with the effects of feed size distribution on characteristic phenomena of confined-bed comminution. Minus 3.35-mm quartz and calcite feeds were prepared by proportionately mixing previously classified narrow-size fractions so as to construct particle size distributions having the Gaudin-...
The dissolution of ilmenite in HClH2O, HClCH3OH and HClC2H5OH systems — A theoretical approach
Türker, Lemi; Goodall, David; Girgin, İsmail (Elsevier BV, 1988-11)
Silicon powders are obtained by laser pyrolysis of silane gas. Temperature and velocity profiles are determined both theoretically and experimentally. The velocimetry consists of a marker technique which measures the propagation time of a perturbation front through the hot reaction zone. In the theoretical model, the coaxial jet expansion undergoing a thermal heating is studied by defining a Dorodnitzin-Illingworth transformation. The results show a decrease of axial velocity as the gas enters the laser hea...
