A method of processing oilfield weighting agents for pneumatic transference including treating a weight material ore with a chemical additive to produce a treated weighting agent and grinding the treated weighting agent to produce a ground treated weighting agent including a substantially homogenized mixture of the chemical additive and a ground weighting agent. Furthermore, the method includes classifying the ground weighting agent by size, discharging the ground treated weighting agent from the mill, and trapping the ground treated weighting agent in a storage vessel. Also, a method of processing oilfield weighting agents for pneumatic transference including grinding a weight material ore in a mill, wherein the grinding produces a ground weighting agent, and discharging the ground weighting agent from the mill. Additionally, the method includes applying a chemical additive to the ground weighting agent to produce a treated ground weighting agent, and trapping the treated ground weighting agent in a storage vessel. |
