The metals industry remains a highly capital intensive sector where reliability and performance of equipment is paramount to ensuring continuous production.

Howden products deliver efficient and effectively as part of the process for customers in ferrous and non-ferrous primary and secondary metals production.

From the treatment of ore to the refining and smelting of metals Howden supplies equipment to meet the demanding requirements of the metals and mineral processing industries. 

Howden products - fans, blowers and turbo-compressors, are found in all sectors from the mine site to smelters and refining plants.  Wherever the plant is located Howden provides reliable and efficient equipment.

Our equipment is used in many applications.  In initial ore treatment fans are used for lixiviation in ore leaching to increase airflows, and fans and blowers are used to provide air for flotation cells. 

Smelting of concentrated base metal ores (copper, lead, zinc) is a process in which fans and the high efficiency Donkin turbo compressors provide air for the reactions.  Centrifugal fans exhaust the gases from the converters and smelters.  

The sulphur dioxide gas produced from smelters is now increasingly captured and converted to sulphuric acid; turbo-compressors are also key components in sulphuric acid production.  

We are major suppliers of fans for alumina refineries and aluminium smelters. Removal of the plant fumes is essential for environmental control.

We have supplied over 40 of our Donkin turbo-compressors for minerals/metal refining applications and many high pressure fans and blowers.

The ExVel(R) range from Howden Turbo Fans are used in MVC evaporators and evaporative crystallisers to concentrate leachates and metal salts in hydrometallurgical refining.
