NASACO Solutions for flotation Solutions for Flotation Learn More About us Nasaco International Ltd. produces and markets chemicals for froth flotation of minerals. Custom Formulations We develop, together with mining companies, chemical formulations that are specific to individual operations. We concentrate on providing solutions to metallurgical problems by developing formulations of frothers, mineral collectors and depressants. Logistics Partner Nasaco operates a fleet of forty ISO tank containers. We also deliver our products in flexi-tanks or, for non-bulk users, in 1000 l IBC containers or in standard drums of 200 l. Powder products are supplied in either 25 kg sacks, big bags or in exceptional cases in bulk. Global Presence Our company is based in Switzerland, and we have subsidiary and associate companies situated in Southern Africa, Mexico and Chile, as well as representative offices in Germany, the US, the Philippines and Australia. Products & Services Nasaco offers a wide range of products and services for your mineral processing needs. Frothers The NASFROTH™ range of alcohol and glycol frothers includes formulations and blends which give application specific products. These are often developed together with our customers. To extend this range, Nasaco is the exclusive distributor of Dowfroth products for Dow Chemical company in the EMEA area. Depressants The NASMIN depressant range is used in the depression of gangue minerals and the control of silicates in the flotation process and are critical to good metallurgical performance. NASMIN depressants are extensively used in the depression of Pyrite and Pyrrhotite as well as for the control of silica and talc minerals. Flocculants In most mineral processes where there is a need for sedimentation, filtration or centrifugation then a flocculant or coagulant is often desired. The NASFLOC range offers a broad spectrum of products ensuring maximum performance and cost efficiency in these applications. Collectors Nasaco has a wide range of collectors for all types of flotation. Our expertise in custom formulation has allowed significant improvements in metallurgy to be made by many of our customers when NASCOL formulations are used. Modifiers A modifier acts on the mineral surface to either activate the surface and thereby promote flotation or to deactivate the surface to make the mineral non-flotable. Nasaco supplies modifiers made from the purest raw materials which give a superior economic advantage. Laboratory Services Nasaco operates a mineral processing laboratory through its Betachem partner in South Africa. The aim of the laboratory is to support the design, development and production of mining chemicals for the group. We provide mineral processing solutions To find out more about our products & services CONTACT US Articles Detailing our research and case studies Laboratory Removing Gangue Minerals A-SEM data is now regularly used to identify the gangue minerals in flotation concentrates and can be used to focus efforts on their removal. Here, we will discuss how the process can be used to reduce gangue minerals in concentrate streams. 10/01/2019/0 Comments Laboratory Operational Mineralogy – A solution to Flotation Problems?
