Understanding Spaghetti Diagrams & Spaghetti Processes
A spaghetti diagram, or spaghetti chart, is a visual representation of how people, products, or data move through a process. It's a type of process model that helps organizations improve operational efficiency and process flow. Spaghetti diagrams use individual lines, or "noodles," to trace the actual path of each movement through ...

Hydrofluoric acid is an aqueous solution of hydrogen fluoride produced by a reaction of fluorspar and sulfuric acid. Hydrofluoric acid is the feedstock used to produce almost all of the organic and inorganic fluorine-bearing chemicals. Hydrofluoric acid also is used in aluminum and uranium processing.4 As of 1989, three facilities actively

Geochemical controls on the enrichment of fluoride in the mine …
PCA reveals that the geochemical controls on the enrichment of F − in mine waters include dissolution of fluoride-bearing minerals and F −-OH − ion exchange; the former process is mainly caused by the decrease in Ca 2+ concentrations resulting from Na + -Ca 2+ cation exchange and mineral precipitation, and the latter process benefits …

Corrosive Environments
Corrosion in aqueous solutions is an electrochemical process, involving ions (electrically charged atoms) and the transfer of electrical charges at the metallic surfaces. Anodes and cathodes occur locally on the surfaces; metal is removed at the anodes (in the form of positively charged ions, i.e. M > M + ). Electrons flow within the metallic ...

Production of Nickel Powder by Hydrometallurgical Processing
The Sherritt (Corefco) refinery in Fort Saskatchewan, Alberta, Canada, provides an example of hydrometallurgical processing used in the production of nickel powder. This refinery commenced operations in 1954, at which time the feedstock for the plant was nickel concentrate from Sherritt's Lynn Lake mining operations in Manitoba.
