I clearly have nothing better do

from the June quarterly - the company had managed with reverse silica flotation to debulk by 40% with 80% recovery

lets say after further improvement with desliming etc we could see 90% recovery and a 50% debulking

that would ultimately result in Gillian ore becoming a new beast with each resultant ton containing 7.74kg Sn and 615kg Fe ( if assumed 100% recovery)

with 90 % recovery 7 kg Sn and probably greater that 600kg Fe

separation of Sn from the fine grind Fe is not that easy ( sadly) but it could be a benefit. Fe grains buried with fine grain casserite impart magnetic properties to the Sn ( odd but true) - so concentration could be improved I guess

So if you want to produce 3000 ton Sn a year on the above or similar you'd need =

(3000 x 1000) / 7 = 428571 t throughput a year ( which can be supplied by a 1mtpa plant easily enough)

that equates to 50 t an hour through a continually roasting/fuming plant which sounds like a lot to me so I'm not sure of my reasoning on this - anyone know anything about rotary kilns?

assuming the feed was pelletised prior to roasting you'd end up with pellets with Fe content in excess of 61% ( much higher depending on much other rubbish was burnt of)

feel free to pull my maths apart

back to dreaming but if you can debulk or increase recoveries even slightly it has an exponential effect on the end result

fuming would be a lot easier if you could even split part of the Fe out of the mix ( which is possible)

and back to waiting
