 Franke Project:
Located 68 km north of the town of Diego de Almagro, the Franke project represents a tangible example of IDT’s ability to develop and build large projects. This equipment is the largest processor - rectifier built in the country, it has a capacity of 70 KA and its design covers all the DC requirements used in the refining and electrowinning naves of the country.
One remarkable element of the equipment is the use of large size semiconductors (SCR), with a 6000 Amp RMS capacity for each element. The security of this equipment considers a physical division between the power and control elements, making a safe and friendly operation. As for its connectivity, the equipment considers a processor with the ability to include IP connection modules, du to this, the connection of the equipment is secure at the level of communication, as is done in direct without connection with the internal IP rectifier’s equipment. It also considers a conductor structure of water cooled copper, technology that helps reducing the size of the equipment, increasing its efficiency.
Milpo Project:
Its first implementation was done in March 2008 and marks a milestone in the history of IDT, as it is the first export equipment manufactured by the company. The equipment, now installed in a plant in Peru, was designed seeking to ensure its operation over time without disturbance and meets much more stringent standards than those required by the client.
Doe Run Project:
The largest copper refinery in Peru deposited their confidence in IDT S.A to develop the design of rectifier equipment specially designed to meet their needs. The geographical location of the plant requires special care in selecting the elements as its installation will be performed at 4800 meters over the sea level.

Matta project:
IDT provided in the second half of 2008 the first Rectifier Transformer system in Chile that is capable to be configured for Refinery and EW processes. With the implementation of this system, the plant will have a capacity of 400 fine copper metric tons per month (TMF / MES), with a lifespan of 10 years. The system is of 2x14, 5kA @ 30-140V, 12 pulses, and water-cooled in electric type container room. The equipment was developed for the Manuel Antonio Matta plant of Enami, located in the Atacama Region, 10 kilometers northeast of Copiapo city and 1 km north of Hernán Videla Lira Foundry. |

Third Rectifier Projects:
Electrowinning technologies have increased the current density in the process, with this increase the rectifier equipment are deprived when delivering all the power the plants require. Looking for a solution to this new technological challenge, IDT has installed in four plants an equipment in addition to existing ones, to operate in parallel and thus increase the total current delivered to the nave. The first experiment was conducted in 2006, at Los Bronces Anglo American plant, adding an equipment of 10,000 amps at each of the two 21 KA equipment. In this way, the current density increased by 24%. The second experiment was conducted in Cerro Dominador mining where there was an additional increase of 4 KA to the nave.
Delta Project:
IDT developed in the first half of 2008, a Transformer-Rectifier system of 2x9kA @ 60V, 12 pulses, air-cooled electric type container room, for Enami Delta plant, located 15 kilometers northeast of Ovalle in Coquimbo Region. The project considers the construction of a concentrator plant of 60 thousand tons per month for sulphide ore and a leaching plant for solvent extraction and electrowinning that will produce 200 tons of cathodes per month, for the treatment of oxides.
Trinidad Project:
In the second half of 2008, IDT developed a Transformer Rectifier system of 2x9kA @ 60V, 12 pulses, air-cooled electric type container room, for Trinidad Mining. The $12 million dollars project is aimed to develop the exploitation of an open pit mine and the construction of a LX-SX-EW processing plant of clean technology with zero effluent, in the Diego de Almagro commune. |
