How Collector Affects Flotation
It appears from all tests run to date that under otherwise constant conditions, increasing the concentration of a given collector increases R and decreases K in a uniform manner. This appears to be true for all collector types and is supported, e.g. by the data of Tables III and IV as well as Figure VIII […]

Flotation and depression control of arsenopyrite through pH and xanthate as the collector. Arsenopyrite Rejection
Flotation: Principles and Applications in Mineral Processing
This is an overview of setting up and conducting a flotation rate test. The test is a means of determining the flotation characteristics of an ore. It is conducted in a laboratory scale cell usually with a volume of two point five litres. The intention is to generate relationships of cumulative recovery, mass pull and […]

Flotation Material Balancing Excel Solver: Mass Balance Calculations Example
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 Simulation & Modelling Software to Improve Grade & Recovery Metallurgy
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 […]

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 […]
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. […]
