This plant washes two different kinds of bauxite ore, one originating from the laterization of gnaisses and another from amphybolites. Both ores have the same behavior in the coarser size fractions but behave differently under 0.355 mm (42# Tyler). In these small sizes, gneissic ores are rich in quartz and amphybolitic ores are rich in iron and titanium bearing ores. The unit operations are: scrubbing of the feed in drum scrubbers, desliming in cyclones, and screening of the scrubbed bauxite in high frequency screens (0.355 mm) - the +0.355 mm product is a final concentrate. The -0.355 mm fraction is desliming in two stage cyclones and goes to a fines gravity concentration circuit of Reichert spirals complemented by magnetic separation of the light product from the spirals. The research work, including mineralogy, process development, batch tests and pilot plant tests, is described and compared...

In order to tackle these determinants, and inspired by WHO's international Healthy Communities/Cities movement, the Network of Healthy Communities of Rio de Janeiro was formed in 2004. The Network is coordinated by the Center for Health Promotion (CEDAPS) and now includes more than 100 community groups and organizations in the state of Rio de Janeiro. Their aim is to promote health, community development and equity through community empowerment, participation, capacity building and advocacy. The paper describes the work that has been done since the Network's inception and the challenges which they face to reach their goals in the context of a country like Brazil. The Network represents an important landmark of how poor populations can ...
