Flotation of Lead Carbonate
Flotation Material Balancing Excel – Solver
For a flotation circuit, material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balancing is to mathematically examine the known flow parameters to solve for the unknown flow parameters. Two main types of material balances are commonly made: design material balance operating plant […]
Rotary Kiln Maintenance
Rotary Kiln Alignment The continuity of operation of a lime sludge kiln requires strict maintenance control. The rotary kiln is among the largest type of moving machines made and is subjected to extreme temperatures, power failures, atmospheric conditions, varying loads, and other operating conditions which affect its wear and alignment. It should be erected under […]
URANIUM METALLURGY
In the metallurgical treatment of uranium ores large tonnages must be handled. Many ores are low grade so it becomes necessary to employ systems which can be operated on a continuous basis at low cost. A vast amount of research has gone into the development of suitable processes. One is solvent extraction, which has proven extremely […]
Uranium Extraction Process
The plant was originally designed to treat uranium ores with low lime-high vanadium content from the Lukachukai Mountains. The process utilized is known as the “Acid Cure” and had been developed for the most part by the AEC to increase recovery of vanadium values. Briefly, it involved “pugging” the ore with 10% water and 400-500 […]
PORTABLE SAMPLING PLANT
A great deal of interest has developed in the new portable sampling plant recently designed by Engineers. The plant is substantially as shown but may be adapted easily to the specific needs of the user at the factory or, because of the versatile design, in the field. The functions of crushing, grinding and sampling are […]

How to Analyse Flotation Test Results
It is pointless to do lab flotation tests if you do not know How to Analyse Flotation Test Results. Here are must read articles on learning float test result evaluation. Mineralogy & Flotation: Floatability VS Selectivity Test Assessment Flotation Kinetics: Mass & Water Recovery VS Entrainment & Mineralogy Timed Flotation Test: Concentrate Collection & Cumulative Grade […]
Parting the Assay Buttons
The assay buttons are flattened by a hammer weighing about 7 lbs., with a convex face, on an anvil kept quite bright and clean and used for this purpose only. A heavy blow is first delivered on the centre of the button, the diameter of which is thereby increased to nearly that of a threepenny […]
Weighing Gold for Assay Checks & Proofs
The balance must readily indicate differences of 0.005 per 1,000, or 1/40 milligramme, with a weight of ½ gramme in each pan. The “checks” or “proofs” (vide infra) are weighed first, and their mean excess or deficiency in weight applied as a correction to all the cornets worked with them. This may be done by means […]
