You forgot the multipier - how many tonnes of sc6 is required for this carbonate. It could be as high as 8. For PLL hydroxide is around 6.5 using the metso outotec method. i.e. less sc6 for a more expensive product. The critical aspect for feasibility is the sc6: carbonate price ratio as well as capex. PLL used a favourable low ratio. If 8 tonnes of sc6 at $5000 is used that gives you costs of $42952. Not a very good margin. If its 7.5 tonnes $40 452. It becomes more cost effective if the sc6 is cheaper relative to the price of carbonate.
