Process engineer here working in coal industry. In my experience, "communication" is by far the most time consuming (and important) activity during work. This involves communicating with operators to make necessary changes or plans, handover communications (for the shift and during the roster change) with other team members, communication regarding safety, maintenance plans, mining plans etc. Regular communications with corporate offices and marketing team.
The next on the list would process data analysis. Understanding how the plant is actually performing as compared to the expectation for the day, week or month. Then comes the ongoing improvement projects. Planning them, setting them up and coordinating with different internal and external stakeholders to achieve the objectives.
This is all the stuff I'm involved in on a day to day basis. I assume it will change depending on your role, commodity and region you work in. Keen to hear others' experience.
The choice of suitable float-sink bath densities is crucial, more points are needed around the expected cutpoint to get a reliable estimate of Ep, fewer points further away. A rule of thumb is that density increments should be less than 2.5 x expected Ep.
For example, for coarse (+4 mm particles) in a well operated DMC, the expected Ep is around 0.01 or better, hence float-sink analysis RD increments should be no more than 0.025. If expected RD50 is around 1.40 then use 1.350, 1.375, 1.400, 1.425, 1.450, plus some other densities to define the tails of the curve.
There was a paper presented at SACPS a while ago (can't recall the exact details) which discusses the topic in much more detail.
