Method to Measure Lime Content in Cyanide Leach Solution

This term is usually defined as "the alkaline hydrates and half the monocarbonates" whose action is to protect the cyanide from decomposition, by acids developed in the ore and by atmospheric carbon dioxide. Either oxalic acid or a mineral acid may be used as a standard solution. Objections have been raised to the use of oxalic on the ground that it is unstable in weak solutions. This is ...

Measuring toxicity — Science Learning Hub

One such population-level measure is the median lethal dose, LD 50 (lethal dose, 50%). This is defined as the dose required to kill half the members of a specific animal population when entering the animal's body by a particular route. LD 50 is a general indicator of a substance's toxicity within a short space of time. It is a measure of ...
