Ni/Co Electrowinning
Tenova Advanced Technologies (TAT) provides services and proprietary equipment, as well as complete circuit packages for Electrowinning (EW) sections of metal recovery plants for the mining industry. TAT designs Tankhouses of all sizes, from those for small operations to large-scale, manual, and automated systems.
Overview
Tenova Advanced Technologies (TAT) offers differentiated, project-specific process technologies based on decades of research, equipment design and project execution. Advanced solutions include solvent extraction (SX) and electrowinning (EW) for the mining and chemical industries, membrane circuits, in-house state-of-the-art R&D facilities, expertise in minerals beneficiation as well as phosphate processing from ore to purified phosphoric acid and salts. TAT designs EW Tankhouses of all sizes, based on both manual and automated systems. The EW packages supplied by TAT include TAT’s Crossflow Electrolytic Cell (“TENOCELLTMTM”) and anode double contact bus bar (“TENOBARTMTM”) and “Buttons” technology
Technical Data
TENOCELLTM
TAT’s redesigned cells provide an improved flow pattern around each cathode resulting in improved cathode quality.
Innovation
TENOBARTM
TAT designed its owned intercell bus bar system in order to enhance the current distribution and efficiency through the EW cell. Optimizing the copper weight per Cathode and decreasing costs. The TENOBARTM system includes an equalizing bar permitting double contact on the anode and therefore:
- Decreases stray currents
- Increases the anode life
- Increases copper quality.
- Decreases electrical energy consumption
“BUTTONS" TECHNOLOGY
When Co or Ni plate out from Sulphate solutions a lot of stresses are created in the metal, meaning that it will not attach easily to the cathode, necessitating the use of starter sheets for Nickel or “wrapping” the metal around the cathode for Co which then has to be chiseled off.
Tenova’s “Buttons” technology uses masked cathodes, the metal plates out as round “Buttons” on the unmasked areas of the Cathode. Even though the “Buttons” are firmly attached the Cathode they can be stripped with ease, yielding an attractive, regular highly saleable product.
