Dec 06, 2017 Some columns were sampled every 20 second. Others were sampled on a hourly base. The second and third columns are quality measures of the iron ore pulp right before it is fed into the flotation plant. Column 4 until column 8 are the most important variables that impact in the ore quality in the end of the process.
