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 […]
Flotation Software to Improve Grade and Recovery
In this video EMC Supasim flotation simulation program is used to simulate the performance of a copper lead zinc plant in southern Spain. Flotation kinetics of key streams are generated by conducting bench scale rate tests on either a laboratory prepared sample of mill feed or grab samples of pulp taken from the plant. And […]
Timed Flotation Test & Cumulative Grade Recovery Curve
Apart from conducting a rate test in the correct manner, it’s important to collect the right number of concentrates and at the right times; doing this will ensure that the data you generate maximizes your analysis of flotation response. To properly define the relationship between recovery and time, you need a minimum of four concentrates […]
Mineralogy & Flotation: Floatability VS Selectivity Test Assessment
Mineralogy is the driving force behind flotation performance. A flotation batch and rate test measures this as mass pull recovery and concentrate grade. The real data from a rate test can be processed to determine the flotation kinetics of metal, mineral and gangue. What we cover here is what are kinetics and what do they mean. […]
Flotation Kinetics: Mass Recovery vs Entrainment
This covers the recovery of entrained solids with water and the relationship between mineralogy and flotation performance; both are described in terms of flotation kinetics. The starting points for the relationship between mass and water recovery other products of a flotation rate test. In addition to concentrate mass, metal or mineral and floatable gangue. If […]
Density Determinatons
To find weight of a given volume of sand or similar material. In cases where it is not convenient to weigh the entire charge direct, the wet and dry weight of a charge is often ascertained by allowing a vessel of known capacity, say a large cubical or cylindrical box, to be filled at the […]
Grind Size & Liberation for Optimum Flotation Recovery
Here is a trick for knowing if your flotation feed grind size is fine enough to achieve adequate mineral liberation without doing a full mineralogy study. If your key mineral is sufficiently liberated, it should float and be recovered in the first few minutes in an initial %mass that stabilizes quickly = the green curve. […]
The Geometallurgy Book Applied
The study is not intended to be a complete geometallurgy book, but it certainly is a great example of applied geometallurgy. It was conducted on the Caribou deposit in New Brunswick, which is a Zn-Pb-Cu-Ag volcanogenic massive sulphide deposit (VMS). VMS deposits form on the seafloor at divergent plate boundaries from hydrothermal vents (e.g. black […]
Mechanical Tools used in Metallurgy
The writer of this paper will realizes that the majority of engineering and metallurgical works have from time to time evolved mechanical devices which are of great value as regards application in an operating plant. Many of these devices would not be apparent to an individual making a brief inspection of works such as these, […]
