Palabora Mining Company supplies 35% of the world’s demand with a life span of 20-30 years. Alternative African supplies are also available from mines in Zimbabwe and Uganda.
Crude vermiculite from the Palabora mine consists of golden/brown flakes which are carefully classified into five grades – each having a specified range of particle sizes. The coarsest grade comprises particles ranging between 8mm and 2.8mm, while the finest grade consists of particles between 0.710mm and 0.250mm in size.
Vermiculite is defined by ‘grades’ which indicate the particle size. V-Core will be using only smaller particle sizes and as such will not be affected by any shortage of supply of the less readily available large grade product.
