Book Description
This report deals with the practical application of the plasma-jet technique of spectrochemical analysis to the determination of the following: iron and chromium in leach liquor from chromite ore; major base metals in leach liquor from chlorinated chromite ore; silicon, aluminium, calcium, magnesium, and iron in cleaner concentrates, slags, and tailings; and platinum-group metals and gold in synthetic solutions. Brief details of the methods used for the different types of samples are given. Except for the determination of platinum-group metals and gold in the presence of base metals, the method was generally satisfactory, being more precise and reliable than the technique in which a dc arc is used on a powdered sample. However, the sensitivity is not as good and the limits of detection are not as low. These disadvantages will probably be overcome by the use of the recently developed induction-coupled high-frequency plasma torch.
