Examples of sulfur concentrate spectra               Examples of original (middle) ore spectrum:           Tailings instance                                                             

Examples of sulfur working curve:

According to the technological conditions of the concentrator, curve calibration is carried out for pulp samples at different technological stages.

Mainly: concentrate curve, original (middle) ore curve, tailings curve. 20 corresponding standard samples should be prepared for each working curve.

A cup measurement method using pulp after preliminary dehydration, realize the request of error is less than 50%. The whole sample preparation analysis time is less than 5 minutes, in order to solve the fineness on the result of analysis, using the same technology section of the characteristics of the sample fineness were small, calibration samples for different process section curves and sample measurement method.
