Treadwell Gold: An Alaska Saga of Riches and Ruin

A century in the past, Treadwell, Alaska, was once a featured cease on steamship cruises, a wealthy, up to date city that used to be the main well known and proud in all Alaska. Its wealth, even though, was once based at the remarkably efficient gold mines on Douglas Island, and while these caved in and flooded within the early a long time of the 20 th century, Treadwell sank into relative obscurity.

Enhanced Oil Recovery: Field Planning and Development Strategies

Enhanced-Oil restoration (EOR) reviews fascinated about asset acquisition or rejuvenation contain a mixture of complicated judgements, utilizing diverse information resources. EOR initiatives were generally linked to excessive CAPEX and OPEX, in addition to excessive monetary chance, which are inclined to restrict the variety of EOR tasks introduced.

Data X Strategien: Data Warehouse, Data Mining und operationale Systeme für die Praxis

Auf der Grundlage aktueller Entwicklungen der Wirtschaftsinformatik stellen die Autoren Konzepte dar, die als Richtlinie für die künftige Entwicklung von einem die operationalen Systeme, information Warehouse-, Informations-, Experten- und info Mining Systeme umfassenden Anwendungssystem dienen können. Neben notwendigen theoretischen Aspekten wird basierend auf der umfangreichen praktischen Erfahrung der Autoren in der Anwendungsentwicklung für Kreditinstitute ein konkreter Praxisbezug hergestellt.

85 mm particle size fractions. I. (acid insoluble) rejection, the presence of picobubbles significantly increased the P2O5 recovery by about 7% up to about 25%. 0%. , 2001). The phosphate matrix in Florida is a composite of sand, clay, and phosphate. The clay in phosphate ore is usually washed and the phosphate ore is classified into three major size fractions. The coarse (+1180 mm) portion is primarily phosphate pebble and does not require further upgrading. The fine (–106 mm) portion that contains virtually all of the clay minerals is discarded in the hydrocyclone overflow (Patrick and Albarelli, 1995).

A polypropylene glycol frother (F-507) was used for the coarse phosphate flotation tests. 5. The flotation feed was conditioned for three minutes at a predetermined 75% solids concentration using a mechanical agitator. The conditioned phosphate sample was diluted to 25% solids content by weight and fed into the flotation column through a peristaltic pump. Figure 1 shows a schematic of the specially designed picobubble enhanced coarse phosphate froth flotation column of 5 cm in diameter. The column was integrated with a hydrodynamic cavitation tube to produce picobubbles.

CHAPTER 3 . . . . . . . 18 mm) remains a recognized challenge although some efforts have been made to improve the flotation process. Previous studies have shown that coarse particle flotation performance can be enhanced by picobubbles generated by hydrodynamic cavitation. In this work, a picobubble enhanced flotation column has been developed for enhancing recovery of coarse phosphate particles.
