Assaying Thallium Determination Method

Thallium is a rare metal, found in small quantities in some varieties of iron and copper pyrites, and in some lithia micas. It resembles lead in appearance. Its compounds resemble the salts of the alkalies in some respects; and, in others, those of the heavy metals. It is detected by the green colour which its salts impart to the flame. This, when examined with the spectroscope, shows only one ...

Zinc smelting

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Thallium in Soils and Stream Sediments of a Zn−Pb Mining ...

Sep 11, 2003· Thallium was determined in 120 samples of soil and 30 samples of stream sediments from the southeastern part of the Silesian-Cracowian zinc−lead ore deposits. Soil samples were taken from topsoils (0.0−0.2 m) and bottom soils (0.8 and 1.0 m). Thallium was determined by flow-injection−differential-pulse anodic stripping voltammetry. The samples were decomposed sequentially …
