Globe Metals and Mining (ASX:GBE) has achieved improvements to grade and recovery with the completion of the Kanyika demonstration pilot plant at Guangzhou Research Institute of Non‐Ferrous Metals in China.

The plant was undertaken as part of optimisation work to complete the Definitive Feasibility Study for the Kanyika Niobium Project in Malawi. It produced concentrate averaging 24% Nb2O5 and recovery averaging 77%.

The flotation process is now optimised and the flowsheet substantially derisked. Concentrate grades of up to 35% are achievable.

These results validate the results of earlier optimisation tests by demonstrating an effective improvement in concentrate grades and increases in Nb2O5 recoveries.

This represents a significant de‐risking of the flowsheet as the test results were achieved under continuous and steady state conditions.

A significant amount of process data was collected during operation of the plant to aid further engineering design in a Front‐End Engineering Design phase prior to plant construction.

The data collected confirms the concentrator design undertaken in 2012, with minor improvements likely to be implemented in the reagent preparation area and in the sizing of flotation cells.

Kanyika has a total Resource of 60 million tonnes at 2,900ppm Nb2O5 at a 1,500ppm Nb2O5 cut-off.
