Jeez I hope you're better at making sense of complex processes in your day job.

Firstly they're still perfecting the process, and secondly they recover the gold in the slag from a resmelt of the slag.

To say "Is BBX any closer to solving the metallurgical riddle" demonstrates your ignorance and\or your intention to downramp. Of course BBX are analysing of the results to perfect the process and are using a team of expert chemists and metallurgists to determine a solution. There are so many variables that it will be very complicated with a huge matrix of possible permutations.

As they get closer to a solution those recovery grades are only going to increase and I'm sure they are going to increase in a big way if they can get a 500% increase from tweak in the extraction technique.
