Recovery of Tungsten Values from Low Grade Ore-II

Approach adopted in new technology to evade technological gap in the existing one

The new technology developed at the National Metallurgical Laboratory, Jamshedpur adopts an integrated approach combining physical and chemical beneficiation methods to get the final product : ammonium para tungstate. In order to avoid tungsten losses in the fine size ranges, prior to final concentration, pre-concentration of the ore is carried out at relatively coarser size.

Advantage

The advantages of this technology includes the following

Higher recovery of tungsten values and the process results in the final product as ammonium para tungstate by a combination of physical & chemical methods.

Reductions in energy towards comminution of ore by carrying out pre-concentration at relatively coarser size.

Reduction in water consumption because pre-concentration is a dry processing step etc.

Brief description

Extensive characterisation and physical & chemical beneficiation studies were undertaken at the National Metallurgical Laboratory, Jamshedpur on different tungsten ore samples from a typically low grade deposit located in Degana, Rajasthan, India. Based on these studies a process has been developed for the recovery of tungsten values from the low grade tungsten ore. The process basically consists of pre-concentration of the ore at relatively coarser size by dry magnetic separation, further upgradation by gravity methods followed by chemical processing to ammonium para tungatate.
