Method of froth flotation testing. Part 1: Laboratory procedure” is the translation of ISO 8858-1:1990 “Hard coal. Froth flotation testing - Part 1: Laboratory procedure” with certain editorial changes. The standard establishes the methods of carrying out the laboratory procedure of froth flotation of fine coal having a lump size of less than 0,5 mm. These methods provide a means of evaluating general flotation characteristics of coal under specified conditions. The developed national standard ДСТУ ISO 9931 “Coal. Sampling of pulverized coal conveyed by gases in direct fired coal systems” is the translation of ISO 9931:1991 “Coal - Sampling of pulverized coal conveyed by gases in direct fired coal systems” with certain editorial changes.
