Lightnin has 90 years of unrivaled experience in industrial mixing technology, process knowledge, Lightnin Mixers - Getting the Job Done Right and technological innovation. Lightnin enjoys a global reputation for durable, long-lasting mixers, agitators, aerators, and flocculators for fluid process systems. We offer a full spectrum In Mining and Minerals Lightnin has developed many of the mixing techniques considered standard for minerals recovery. Innovative research and testing for of impeller designs for diverse applications. In thousands of...

Typical product applications Lightnin Technology SPX has a process solution for a wide variety of mixing applications. Mixing applications can be broken down into the following mixing With Lightnin products, SPX has pioneered many of the mixing techniques now duties: liquid-liquid, liquid-solid, gas-liquid-solid considered standard for minerals recovery. From individual agitators for simple and uid motion. Many applications are often solids suspension applications; to the exacting demands of High Pressure a combination of these duties and thus having Oxidative leaching and to the design of...

Gold Recovery For Pressure Oxidation (POX) Autoclave applications, SPX’s Lightnin brand Carbon-in-pulp (CIP) is the sequential leach and has one of the largest successful agitator installed base in the world. POX adsorption of gold from ore. During the leach, pulp applications not only cover gold but also other metals such as copper and flows through agitated tanks where sodium cyanide platinum. Through the use of lab testing and computational uid dynamics, we and oxygen dissolve the gold into solution. The offer process optimization for POX autoclave applications, which includes solution...

ALU M I NA Ground bauxite is mixed with recycled caustic soda solution (“spent liquor”) and fed into digesters. With Alumina Precipitators proper agitation, the alumina goes into solution as sodium aluminate. In the precipitation train, seed particles of alumina trihydrate are introduced to precipitate relatively pure alumina trihydrate crystals from the cooled, super-saturated solution. A low shear draft tube mixer maintains slurry homogeneity at minimum power while minimizing crystal degradation. SPX’s Lightnin Draft Tube Circulator has become a common method of suspending alumina hydrate...

Nickel is found in sulphide or in laterite deposits. Hydrometallurgical process- Lightnin has pioneered the agitation in HPAL es for nickel sulphide use the ammonia leach process and either the Caron autoclaves with the use of A313 impellers for the blending of sulphuric acid with the slurry. This Process or the High Pressure Acid Leach (HPAL) for the nickel laterites. material needs to be uniformly blended into the High Pressure Acid Leach (HPAL) autoclaves dissolve the nickel contained in the laterite ore by adding sulphuric acid at high temperatures, typically 265 - 275°C (510 – 525°F)...

Reliability By Design SPX understands that when it comes to efcient process plant operations, equipment reliability is of paramount importance. As a longstanding member of AGMA (American Gear Manufacturers Association) SPX’s Lightnin brand recognizes that multi-purpose commercial gearboxes are often poorly suited to Agitator service. For more than 50 years the Lightnin products have utilized proprietary, purpose designed agitator gear drives to ensure dependability and lowest cost of ownership. With more than 1 million units in the eld our operating experience is unsurpassed. SPX’s agitator...

Consulting Services SPX’s Lightnin brand has long supported the need of providing full service mixing support to our valued customers. In today’s business environment of “doing more with less,” local resources at your operation have been stretched or eliminated. At SPX, we recognized this and have increased the level of process support available to our customers. Evaluation and resolution of our customer’s mixing issues has been a core strength for many years at our Lightnin facilities. You can leverage the resources and knowledge base of Lightnin by optimizing your mixing processes and...
