Custom Formulations

In collaboration with mining companies, Nasaco develops chemical blends and formulations that are customized for an individual operation. Using analytical techniques, Nasaco targets specific metallurgical problems and provides solutions for every step of the recovery process. Our company supplies NASROTH frother, NASFLOC flocculant, NASCOL collector NASMIN depressant and modifier formulations and blends. We also represent Dowfroth products from Dow Chemical Company.

Global Presence

Thirty years ago, Nasaco was founded by experienced metallurgical engineers who realized they could improve mineral recovery by utilizing targeted mineralogical analysis tools. Using proprietary software, engineering experience and expertise and their own process of Operational Mineralogy, Nasaco provides mineral processing operations advanced techniques like quantitative scanning electron microscopy.

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.

Logistics Partner

Nasaco delivers precise blends and formulations of flotation reagents, depressants, flocculants and modifiers which are customized for applications specific to your processing plant, mineral collectors and flotation frother needs.

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.

Nasfroth

Frothers are an essential reagent in most flotation reagent suites and directly through their action improve grade, recovery or both in a float circuit.

Nasaco is a major supplier of frothers to the mining industry. The NASFROTH™ range of alcohol and glycol frothers includes formulations and blends which give application specific products. These are often developed toghether with our customers. To extend this range, Nasaco is the exclusive distributor of Dowfroth products for Dow Chemical company in the EMEA area. DOWFROTH™ incorporate a range of glycol and glycol ether frothers.

We develop our formulated frothers together with our customers in our R+D labs and on customer sites. By working together with our customers in this way we can offer specifically designed products for their processes.

Nasmin

Depression of gangue minerals and the control of silicates in the flotation process 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.

Nasmin depressants are based on a range of organic amines and modified polysaccharide and cellulose derivatives.

Nasfloc

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.

As Nasaco specialises in the mining industry it has built its flocculant range based on 20 years’ experience in the field and offers a range of products in the following categories:

Our products include:

The NASFLOC range of performance flocculants and coagulants incorporates a broad distribution of charge density and molecular weight products to enable the treatment of most mineral processing slurries.

All of our flocculants are manufactured and supplied as powder form products which gives the benefit of low dosage, easy handling and cost-effective shipment, whilst or coagulants are all liquid form products making them easy to apply to a process stream.

We understand there are a bewildering number of flocculants on the market and we have included a summary of products by application based on our experience, to help you choose products for initial product screening work. Once you have selected an initial product then we can assist you with further products from the extensive range of charge densities and molecular weights, in order to optimise your application.

To complement our flocculant and coagulant range we also supply make down units to give you the best possible performance from your NASFLOC product.

In mineral processing applications where sedimentation or centrifugation is required, the NASFLOC range offers ultra-high molecular weight products, which ensure maximum performance and cost efficiency in the process.

Our range of medium molecular weight NASFLOC polymers are particular effective on sedimentation applications, where high settlement rates are required, without sacrificing overflow clarities. These products are often the most effective choice when thickener underflow densities need to be well controlled.

Our lower molecular weight NASFLOC polymers are used as filtration reagents on applications such as vacuum filter or belt press applications. By using these low molecular weight flocculants the floc structure is strong enough to withstand the high-pressure conditions whilst developing a permeable structure allowing rapid water release.

Our range of NASFLOC polydadmac and polyamine coagulants are often used in conjunction with our flocculant range where high clay content substrates (or very finely suspended solids) require solid/liquid separation. The overall effect is very high-quality supernatants with improved rates of solid/liquid separation.

Nascol

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 Nasaco formulations are used.

Our collectors are used in the following mineral flotation applications:
