Ann: Magnesium Oxide Production, page-35

At full capacity a 1000tpa plant running 24/7 would be 2.7t per day around 110kgs an hour, so to produce 200kgs over 16 hours is a little off target, granted it's an initial run on world first a technology but shows they have some work to do.
I'm confident once they dial in the plant and get a rhythm going the tonnes will come but like @tropic stated the purity levels and efficiency of the plant are what I'm waiting for. Not to mention the small financial hurdles we have to face.

(fyi I'm as good at mafs as I am spelling so feel free to correct to my work)
