I turned to Bob Coker for his description of diffusion of moisture into pulp cables. He is an expert in maintaining the copper infrastructure, especially pulp cables under air pressure. Bob stated: I've been in the business more than 52 years and spent much of that time dealing with cable maintenance and cable pressurization.

The use of nitrogen to replace air in the flotation stage of plants in which molybdenite is separated from copper sulfides was introduced in the mid-1980s in North and South American to minimize oxidation of the NaHS used to depress copper sulfides. ... Metallurgical improvement of a lead/copper flotation stage by pulp potential control. Int. …
This aeration stage was included to restore the pulp potential to the natural or air-set potential prior to flotation. Collector was then added and the pulp conditioned for a further 5 min. When cyanide was used, it was added after the pH was adjusted and before the pulp was aerated, and the pulp was conditioned for an additional 2 min.

Note the appearance of the clean pyrite signal near 707eV at the normal air-set pulp potential of +200mV. I I 704.0 700.0 Other examples of the detection of increased pyrite exposure have been found in Eh adjustment of the pulp solution for Elura between -400mV and +400inV. Pyrite exposure increases systematically from -400mV to +200mV …
Fig. 3 (a) presents the effect of pulp potential on both concentrate grade and recovery of lead obtained in the batch flotation experiments. In this figure, the x-axis is the absolute change imposed to the potential, ΔEh=Eh–Eh nat.The figure shows that both grade and recovery substantially increased as the pulp potential was increased above …

The flotation behavior of cerussite and galena treated with different dosages of sodium sulfide and 5×10 −5 mol dm −3 amyl xanthate as the collector at pH 9.5 is shown in Fig. 2 a. Complete galena flotation was obtained with sulfide additions smaller than about 2×10 −4 mol dm −3.At this sulfide dosage, however, mineral flotation falls drastically.

These were sulfidization of the pulp prior toflotation and using nitrogen to replace air in flotation. Sulfidization requires pulp potential control to keep this …
Air and nitrogen combinations were used to achieve a set pulp potential, Ep. The Ep quoted is on the Ag/AgCI scale, unless otherwise stated, and refers to that at the onset of flotation. During flotation control of the Ep was relinquished. RESULTS AND DISCUSSION Parameters for Analysis Two measures were used for analyzing the data.
The Malvern Panalytical Zetasizer makes the measurement of zeta potential simple, fast and reproducible. The zeta potential of pulp and other particles in the process may vary for a number of reasons, e.g. changes in refining, pH, pulp source, broke content and quantities of additives used. Typical Paper Manufacturing Plants

The project will produce low-cost biocarbon from paper mill sludge and produce ethylene, which will replace petroleum-based ethylene to synthesize polyethylene. The developed technology will result in at least a 90% decrease in CO 2 emissions from the pulp and paper industry, with the potential to achieve total elimination of CO 2 emissions.

The pH is raised to 12 and the pulp potential set to about −150 mV SHE with nitrogen being used as the carrier gas. The resultant froth concentrate is high in arsenic and needs to be treated to remove the arsenic and recover the copper. 4. Tails from stage 3 are floated at the air-set potential using air and chalcopyrite-bornite is floated off.
