An APIC jig was supplied as part of a contract to provide plant engineering for the complete crushing, screening and jigging plant for iron ore beneficiation. The jig, was at the time of the contract, the largest in the iron ore beneficiation industry in India, and was a fine reference for 4 m wide APIC jigs.

The scope covered the supply of an APIC jig capable of handling three independent size ranges of material. The jig is equipped with state-of-the-art control systems and any size range can be treated without any adjustment to the jig. The jig was provided as part of Jayalaxmi Minerals' greenfield project to establish a beneficiation plant which has an annual throughput of 1.2 million t/yr, converting low grade (<56 % grade FE) to high grade iron ore (>60 % Fe) with 8 to 10 % grade up gradation and 65 % to 70 % recovery.

A jigging plant incorporating a 300 t/h coarse coal APIC jig and bucket elevator was commissioned for ACB at the Dipka Mine and was the second 300 t/h APIC jig supplied to ACB in that year.

The jigging facility was installed at the core of a new expansion phase at the washery. The jig was manufactured and assembled by DELKOR in India. Some of the key components of the plant, mainly the control system, were imported from South Africa.

The modular nature of the facility enabled the washery personnel to easily undertake the assembly. The plant was commissioned by a team comprising engineers from DELKOR, the South African minerals research institute Mintek, and plant operators from the mine, and took only a few weeks.

The coal washery at the mine is one of the largest in India, processing 10 million t/yr of coal using gravity separation techniques. The run-of-mine coal comes from the nearby Gevra - Dipka open-cast mining complex, Asia’s largest mine of this type.
