Beneficiation (or concentration) processes are gener- ally used to upgrade the phosphate content by removing contaminants and barren material prior to further processing. A few ores are of sufficiently high quality to require no further concentration. The natu- rally occurring impurities contained in phosphate rock ore depend heavily on the type of deposit (sedi- mentary or igneous), associated minerals, and the extent of weathering. Major impurities can include organic matter, clay and other fines, siliceous material, carbonates, and iron bearing minerals. These charac- teristics influence the beneficiation processes employed. The removal of fines such as clays and fine-grained aluminium and iron phosphates is usually conducted through a combination of crushing/grinding, scrub- bing, water washing, screening, and/or. | I GOLF DIGEST PUBLICATIONS MUli T H E E NV I RON MEN T Golfer Perceptions 8c Attitudes Concerning the Game and its Relationship with the Environment AGENDA Background Objectives Methodology Overview Headlines A Brief Look At the Respondent Base Significant Findings GOLF DIGEST MllHAIIOIS 9 RESOURCE 2 ci MI R GolfTHE ENVIRONMENT 2008 T Background Objectives Assess comparisons of Avid Golfers with the General Population regarding the perceptions of the game of golf and its relationship with the environment GOLF DIGEST I MIUỈAIIOIỈ K 7 WSOURCe 3 .
