Magnafloc 611 is substituted by Chinafloc A3016 in mining
Magnafloc 611 is a high molecular weight fully anionic polyacrylic flocculant supplied as a free flowing powder
Magnafloc 611 has found application in a wide variety of mineral processing operations where the pH is high. Also as it is essentially nitrogen free its use in brine clarification does not give rise to the formation of nitrogen trichloride in subsequent electrolysis. Applications include:
1. Alkaline leach uranium circuits
2. Brine clarification
3. Flocculation in high pH systems
Dosage depends upon the application but normally lies in the range 2 – 200 g/tonne of dry substrate flocculated.
Physical form White to off-white free flowing powder
Particle size 98 % < 1000 μm
Bulk density Approx. 0.85 g/cm3
pH of 1 % solution at 25 °C Approx. 9.0
Viscosity at 25 °C See graph and table
Nitrogen content < 1000 ppm
Recommended solution concentrations:
Stock solution 0.25 – 0.5 % max.
Feed solution 0.025 – 0.1 % max.
Storage & Shelf life
Magnafloc 611 is at least stable for four years from date of manufacture in its unopened original packaging stored in a cool and dry place.
Stock solution 1 – 2 days
Details on preparation and application can be obtained from a BASF representative.
Shipping & Handling
Magnafloc 611 is available in 25 kg bags and big bags.
Corrosivity towards most standard materials of construction is low, but aluminium and galvanised equipment should be avoided.
Advice and assistance in the running of laboratory and plant tests to select the correct product and determine the best application can be provided by representatives of BASF, who are experienced in mineral processing applications.
Health & Safety
Please refer to the Safety Data Sheet for detailed information concerning product’s hazards and appropriate protective measures in the workplace.
Chinafloc A3016 is a kind of anionic flocculant with high molecular weight and medium hydrolysis degree which can resistnt salt and a certain temperature.as our experience ,it can replace of Magnafloc 611 totally in mineral processing.
