Cast Iron Weight Calculator | MachineMFG
This cast iron weight calculator is based on a cast iron density of 7g/cm³. If the density of your cast iron is not this value, you can enter your own metal density in the metal density input box. Furthermore, you can refer to the metal density table to find the corresponding density values. For more calculations on metal weight, you can use ...
8.2: Precipitation Gravimetry
Calculate the %w/w Fe 3 O 4 in the sample. Solution. A conservation of mass requires that the precipitate of Fe 2 O 3 contain all iron originally in the sample of ore. We know there are 2 moles of Fe per mole of Fe 2 O 3 (FW = 159.69 g/mol) and 3 moles of Fe per mole of Fe 3 O 4 (FW = 231.54 g/mol); thus

Gold Extraction & Recovery Processes
The metallic content of agglomerates is influenced by the gold content, gold recovery, and carbon/ore ratio. For example, it has been determined that ores with 1 g/t of gold will form agglomerates with 1,050 – 1,550 g/t of gold. The recovery can be improved by adding surfactants. This action is similar to the conventional flotation.
