:: Increasing Demand for Bateman in India

Bateman Engineering, through its business unit based in Bangalore (Bateman India), is making increasing inroads into the Indian minerals sector, having recently received a number of contract awards for processing projects, as well as making good progress on major bulk materials handling projects.

US$19 m Gadag Gold Project

The award of the approximately US$19 million lump sum turnkey (LSTK) project by Ramgad Minerals and Metals Ltd, a subsidiary of the Baldota Group, for the Gadag gold project in Karnataka, is India's first private sector gold ore processing plant.

The processing plant, which is scheduled for production in the fourth quarter of 2011, will be designed to treat 1,000 t/day run-of-mine (ROM) oxide ore from the Sangli Open Pit Mines, using a flow sheet comprising crushing, milling, cyanide leaching, activated carbon adsorption and tailing disposal sections.

The scope of work for the project includes engineering design, procurement, construction and commissioning of the processing plant to a level at which the plant can receive ore. Work on the project has started and will be executed by Bateman India, with the process design and engineering of the hydrometallurgical processing plant being provided through Bateman Engineering's groupwide source of expertise and state-of-the-art technologies in gold ore beneficiation. This is in line with the Bateman philosophy of executing projects from the relevant regional office, but drawing on its global expertise and technology base to ensure that its clients receive the best flowsheet design available in the Group worldwide.

US$6.5 m SMBP Project

The approximately US$6.5 million LSTK project for the debottlenecking of the Surla Mine Beneficiation Plant (SMBP) in Goa will increase the capacity of the plant from 200 t/h to 350 t/h and enable it to beneficiate siliceous iron ore.

This plant will therefore be the first of its kind in India as, while siliceous iron ore is abundantly available, its beneficiation has not been carried out before in India due to the very low grade of the iron content.

The project was awarded to Bateman India by VS Dempo, which is a subsidiary of SesaGoa Ltd, part of the giant Vedanta Group. The project award is as a result of a debottlenecking study currently underway by Bateman India of VS Dempo's existing iron ore beneficiation plants: the SMBP, two streams of the Surla Beneficiation plant (SBP) and the new beneficiation plant at Bicholim.

The debottlenecking study for the SMBP plant is already complete and, based on its findings, the LSTK project covers design, engineering and execution, with new equipment to be installed including crushers, screens, ball mills and magnetic separators.

Commissioning is scheduled for the end of January 2011. The execution of the project is being carried out by Bateman India, and the design and engineering is drawing upon Bateman Engineering's groupwide iron ore beneficiation expertise and technologies.

JODA project on schedule

The structural work on the materials handling contract is nearing completion for Tata Steel Limited's expansion programme at Joda Mines in Orissa, India, which doubles the mine's iron ore production to 8 million t/yr. With work more than 80 % complete, the project has achieved an impressive safety record of 1.3 million manhours worked in total as at 30 June 2010, without a lost-time injury.

The scope of work covers the engineering, procurement, construction, including civil and structural work, start-up, commissioning and demonstration of performance tests of the materials handling system. The system will handle iron ore at 6.8 and 10 million t/yr at Joda East Iron Ore Mines, with major components being 10 bunkers (each 800 m3 with Hardox liner), 700 m long belt conveyors (the technology for which was supplied by Bateman Engineered Technologies), hoppers, belt and vibrating feeders, electrical drives and a control system.

Conveyor system for Utkal

Engineering is in progress on the longer of the two conveyors that form part of the USD92.5 million turnkey contract to supply a 19 km overland conveyor system for the greenfields Utkal Alumina project in Tikri, Raigada in Orissa.

The scope of work for Utkal Alumina International Limited (UAIL) covers basic engineering and detailed engineering, design, procurement and fabrication, right through to erection (including civil and structural work), commissioning, performance guarantee test runs and hand-over of the system.

The system is being designed with a rated capacity of 2,850 t/h and is the "life line" for the alumina plant, supplying the bauxite ore from the mine to the plant. The system comprises two conveyors - one 16 km in length and the other 3.5 km long. An intermediate transfer point and unloading station, including silos, buildings, etc, are also being supplied with complete electrical and instrumentation systems.

This project is continuing the excellent safety record of Bateman India, with no safety incidents to date on site.

Crushing plant for UAIL

Bateman India has also been contracted by UAIL to install a fixed crushing plant to feed the new Alumina Refinery at Tikri. The project is reaching 50 % completion, with the majority of the engineering and procurement complete and civil works at site having commenced.

The LSTK contract covers design, supply, installation and commissioning, along with related civil and structural works.
