Quantitative Leaching of a Nigerian Iron Ore in Hydrochloric Acid
A study on the quantitative leaching of iron ore in hydrochloric acid solution has been undertaken. The elemental composition of the iron ore was also carried out using ICP-MS technique. The major elements in the iron ore include: Fe(66.7%); Al (0.2%); Si (5.2%); Ti (0.02%) and O (28.0%). Some traces of V, Ni, Zn, Ce, Cr, La, Y and Zr were also found. The effects of contact time, acid concentra...
متن کاملGALENA: Tabular DCG Parsing for Natural Languages
We present a deenite clause based parsing environment for natural languages, whose operational model is the dynamic interpretation of logical push-down automata. We attempt to brieey explain our design decisions in terms of a set of properties that practical natural language processing systems should incorporate. The aim is to show both the advantages and the drawbacks of our approach.
متن کاملGalena Lead Isotope Model for Vancouver Island*
This paper demonstrates how a galena lead isotope model can be used to make decisions about the age and origin of ore deposits on Vancouver Island. To build this model we draw on the galena data of Table 1-9-1 (compare Andrew and Godwin, in press a, b, c and Godwin et al., 1988). Galena lead isotope data from Vancouver Island do not show a systematic evolution with time. Therefore they cannot b...
متن کاملEffects of Annealing on Deformation Textures in Galena
Experimental annealing of galena samples with known deformation histories shows that this mineral has the necessary properties to be a valuable source of information about low-grade deformational environments. Annealed galena displays recovery and/or recrystallization features dependent upon the type of texture inherited from the tectonic event, which in turn is closely linked to deformation te...
متن کاملHydrophobic Flocculation of Galena Fines in Aqueous Suspensions.
The hydrophobic flocculation of galena fines induced by potassium amyl xanthate (PAX) in aqueous suspensions has been studied using laser diffraction, electrophoretic light scattering, contact angle, and microflotation measurements. The measurements were performed on <2 µm, 2-5 µm, 5-10 µm, and <30 µm size galena by varying several parameters, including PAX concentration, pH, original particle ...
