Remove Trash from Flotation Circuit via Screen-Box in Grinding Circuit
An on-stream analyzer and small regrind cyclones (their small 1/2″ Apexes) were being plugged by trash coming from the underground mine in the form of wood and plastic. A simple solution was to install a homemade screen box on the cyclone overflow prior to feeding flotation. The operator cleans it daily, thanks to the overhead […]
Stoichiometric Assays to Mineral Conversion Factors – Stoichiometric
Use the conversion factors in this Table which uses Stoichiometry to approximately convert metal assays to minerals. If you know your sample has only Chalcopyrite as a copper specie, you multiple the %Cu it assays by 2.88 to get the %Chalcopyrite of the sample.
Schuhmann Plot
A Schuhmann Plot help smooth out particle size data. I attach a graph created for a settling test of flotation concentrates. You draw/create a Schuhmann Plot using the details found in http://technology.infomine.com/enviromine/ard/mineralogy/Size%20&%20Liberation.htm and http://www.chem.mtu.edu/chem_eng/faculty/kawatra/CM2200_2009_HW_3_sizedist.pdf
