SNF provides specialty chemicals and services for mineral processing and the metallurgical Industry.
SNF products are used at each stage of the mine and of the metallurgical processing plant.
Manufacturing plants using a wet process will use specialty mining reagents or flocculants at any stage of their operation: mining and primary crushing, beneficiation plant including flotation concentrators, hydrometallurgical and metal refining processes, tailings and effluent treatment.
In pyrometallurgy, SNF products are used mainly for pelletization and sintering (iron ore, nickel sintering). Specialty chemicals would be used for the removal of heavy metals from liquid effluent produced by off-gas circuits.
In material handling, SNF provides technical solutions for dust reduction (tracks, mines, stockpiles and shipping port), dredging, hydraulic transport of slurries and antiscaling.
SNF products are used worldwide, for the Copper, Alumina, Nickel, Gold, Iron ore, Coal, Phosphate, Industrial minerals, Industrial sands Aggregates. SNF is not only a manufacturer of products but is there to contribute with its customers to reduce capital and operational costs of processing plants, reduce energy and water consumption and minimize its environmental footprint. The environment, health and safety management is of capital importance to our group and is a fundamental aspect of any good business practice. SNF engineers and researchers work on development of new product technologies which address these issues. In the field, our technical experts provide the necessary services to achieve these objectives
SNF manufacture flotation products. Xanthates collectors are widely used in the world for the separation of metal sulfides: copper, nickel lead, gold and zinc. This is a key business within SNF with two modern production plants. Products are commercialized under the FLOMIN C brand. Products are mainly sold in pellets forms in various packaging forms (from drums to jumbo bags).
SNF manufacture polyacrylates and polyacrylamide products. Those products would be used either as dispersants or flocculants, depending on the molecular weight.
The dispersant range are used as antiscale agent, rhreology modifiers. This is the FLOSPERSE range of products. The FLOGRADE products are customized dispersants used for the ore comminution. They would help to reduce the grinding energy or to increase ore throughput.
The flocculant range would start from non-ionic products, as used in the nickel or coal industry to high anionic products (FLOPAM) which are mainly used in the alumina industry (FLOMIN AL range). SNF manufacture as well hydroxamated flocculants for the alumina industry. For preleach thickeners and tailing thickeners, SNF manufacture anionic terpolymers flocculants with different anionic charges (DRYFLOC), those products would enable the production of higher slurry underflow, exhibiting low yield stress. This would lead to savings in pump energy, water consumption, reagent consumption, in increased recovery/plant throughput.
SNF manufacture cationic flocculants which in some occasion can be used within the mining industry. The full range of cationic charge is available.
SNF Polyamine and Polydadmac polymers are used as coagulants, they would help to clarify mining effluents.
Supplying quality products to any mine site is not enough. Service to the mining industry is key for us. Our sales and technical representatives is available all over the world. Our engineers have a wide background: metallurgists, process engineers, mining production managers, engineering. This network of competencies and field experience is available 24/24, 7 days. We are a team without borders: the right competency will be deployed at the right place and at the right time. We have created internally Emergency Response Teams to provide answers to our customers.
