Pioneer stated earlier in the project that the first drill holes sample appeared to be about 20m thick and estimated to contain around 35% spodumene. Facilitated by calcination, decrepitation expands the spodumenes crystal structure by about 30%, ultimately allowing the otherwise chemically inert ore to react with sulfuric acid., In processing spodumene concentrate, calcination causes decrepitation at temperatures between 1075 1100 C. Temperature control during calcination is crucial to the success of the process; if temperatures are allowed to approach anywhere near 1400 C, undesirable formations between the alpha spodumene and other silicates can occur (referred to as eutectics).. As one of the two key feedstocks for the production of lithium chemicals, spodumene from hard rock is processed to lithium hydroxide or carbonate by convertors, the vast majority of which are in China. By 2025, experts anticipate demand is likely to increase by a staggering 73%.. endobj
