Depending on carry-over of the material, liquor ratios of 1:3.6 in partially flooded vessels are now possible in mill practice.
Chapters cover flotation fundamentals; the mechanism of flotation; sulphide mineral flotation; thiol collector chemistry; commercial sulphhydryl collectors; properties of flotation froths; chemical properties of frothers; flotation modifiers; depression and activation of sulphides; mill test case histories; sulphide mill practice; non-metallic mineral flotation; and flotation testing.
Depending on carry-over of the material, liquor ratios of 1:3.6 in partially flooded vessels are now possible in mill practice. Improved rinsing functions are said to allow reduction of after-treatment time by almost one hour.
Wood and chip quality aren't exactly obvious under the banner "new technology," so perhaps what we really need is more old technology put into good mill practice. In recent work on the first implementation of Paprilox PS/AQ pulping, our team showed that the total yield gain over kraft could be as high as 7% (wood to brownstock) if everything was optimized.

Participants will study how kraft pulping occurs in mill practice; interactions of wood, chemicals, heat, and mechanical variables on pulping results; comparison of new methods for kappa number measurement and digester control strategies; how to use mountains of mill process data to find interactions and solve problems; step-by-step analysis of changes in pulp properties during the pulping process; and options for preserving pulp strength potential.

Mr Redwood said: "We do not wish to see Victorian mill practices reintroduced."
However, it is important to remember that rough mill practices can influence the quantity or volume of product manufactured from a given amount of lumber and labor through yield gain (or loss).
The current focus of the yield improvement campaign is to identify yield performance ranges based on actual production statistics then correlate the yield data with information on rough mill practices to establish how different operational factors impact yield.
