An evaluation of refrigeration (7°C) to prevent falsely high plasma or serum zinc concentrations owing to elapsed time between blood collection and centrifugation was performed. At room temperature (23°C), both plasma and serum zinc concentrations increased significantly, if blood samples were stored uncentrifuged. Plasma zinc concentrations increased 6.3% at 1 h and 40.7% at 24 h, whereas

Monomineral and compound fractions, ore material and concentrates are used to study the effect of basic processing factors on mineral separation. The key criteria are determined to choose a method of selective extraction of minerals and their species in various cycles of a process flow chart. Such key criteria include: degree of activating effect of copper minerals on other sulfides
