Froth Flotation Handbook
What is Flotation Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float Minerals that float have a […]

Common & Basic Formulas for Mineral Processing Calculations
The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a […]
Method For Measuring Air Hold-Up In Cells
A very unique and simple way of measuring or comparing the amount of air that is working its way up through the pulp of any flotation cell is as follows: A 500 cc or 1000 cc graduated cylinder (smaller size should be used if test is to be made on a laboratory size cell). A […]
Bulk Storage Hopper Flow & Feeder
The performance of Bulk storage hoppers and silos is sensitive to the nature of their contents so consideration must first be given to the physical properties with respect to the operational requirements of the system. See the I.Mech.E publication: – ‘Guide to the specification of bulk solids for storage and handling applications’. by Lyn Bates […]
Mineral Concentrate Marketing – Treatment Charges & Penalties
The object of this Concentrate Marketing post is to draw attention to the benefits of modern milling practice, thus enabling the miner and mill operator to plan their operations so as to net the highest commercial return. By making such products as will be in demand, they may thus take advantage of conditions existing in the […]

How to Size a Thickener
Knowing how to size a thickener and determine the capacity required to handle a pre-determined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp. The settling rate of any pulp is easily determined by simple laboratory tests […]
