Malaysian Feldspar: Evaluation and Processing of

2020-2-14 · Abstract: Several known feldspar deposits in Peninsular Malaysia were evaluated in the present study, and the potential use of the feldspar in local industries was assessed. The main objective of the present investigation was to identify deposits that can be exploited and processed to reduce the reliance of the region on imported feldspar. The specimens were characterised, and suitable upgrading processing techniques were assessed. The deposits were characterised by chemical composition analysis, button-making inspection and grinding tests. The primary upgrading techniques evaluated in the current investigation include magnetic separation and physical-chemical processes. Based on the results of the present study, potential uses of local feldspar
