Cutoff grade estimationQueensMineDesignWiki

 · CutOff grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore while material below this grade is considered to be waste. Although in a variety of units can be used the cutoff grade is usually expressed as

Selective masking and demasking for the stepwise

200836 · A complexometric method based on selective masking and demasking has been developed for the rapid determination of aluminium lead and zinc from the same solution in glass and glass frit samples. The determination is carried out using potassium cyanide to mask zinc and excess disodium salt of EDTA to mask lead and aluminium. The excess EDTA was titrated with standard Mn(II)SO4

Lead and ZincEnergy

 · Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A leadzinc ore may also contain lead sulfide zinc sulfide iron sulfide iron carbonate and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
