Overview

SG Controls provided electrical and control systems design and commissioning support for the Grand Cote Mineral Sands facility in Senegal, Africa. The new facilities included a Wet Concentrator Plant, Wet Mill, Dry Mill and train loadout. Since completion of control systems commissioning last year, SG Controls have continued to assist with upgrades and fault finding support. By involving the same staff throughout the commissioning and support phases of the project, SG Controls have been able to complete all assigned tasks with efficiency and to a very high standard.

Profile

  • The Grand Cote Operation is located approximately 120 km North of Senegal’s capital city, Dakar
  • The mineral sands project produces two grades of ilmenite, zircon, rutile and leucoxene
  • The process consists of a floating dredge which pumps sand containing minerals to the wet concentrator plant, (WCP)
  • The dredge manoeuvres using four winches connected to land based anchors and GPS tracking
  • The heavy mineral concentrate, (HMC), produced by the WCP, is then processed by the mineral separation plant
  • The mineral products are loaded onto trains and transported to Dakar port for ship loading
  • Grande Cote has an expected life of more than 25 years.

Capacity

  • The designed nameplate flowrate of sand from the dredge is 7,000 dry tonnes per hour
  • It is estimated that on a yearly basis, 50M tons of Sand will be extracted resulting in 85,000 tons of Zircon, 15,00 tons of rutile and leucoxene and 570,00 tons of ilmenite -making Senegal one of the world’s largest procedures of these minerals
  • Designed WCP output is 126 dry tonnes per hour of HMC

Scope of work

The new plant required construction and commissioning of

  • Wet Concentrator Plant including HV & LV Siemens VSDs
  • Wet Mill – wet high-intensity magnetic separators (WHIMS) and shaker tables
  • Dry Mill – drying, screening, high tension rolling, electrostatic plate and magnetic separation
  • Product handling – container and bulk bag loading
  • Train loadout
  • Deep bore and containment bores – remotely located, controlled from the WCP control room over radio communications

Our involvement

  • SG Controls provided electrical and controls support for a BEC Engineering designed electrical and control system
  • As the plant continues to ramp up production, SG Controls continues to provide onsite support
