The literature on the processing of phosphate rocks by flotation is critically reviewed. Commonly used collectors depressants auxiliary reagents and their mixtures in the flotation of the phosphate ores were tabulated. The advantages and disadvantages of the reagent type and structure (e.g. ionic and nonionic) on flotation were criticized.
They can be used in column mechanical and conventional floatation systems for reverse floatation of impurities such as silica alumina phosphate and sulphur from different types of ores. Our environmentally-friendly coal flotation reagent has been developed to effectively reduce ash content and other impurities in coal fines.

2012-1-2 With the depleting reserves of high-grade iron ore in the world froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry froth flotation has been established as an efficient method to remove impurities from iron ore.
2020-4-8 Iron ore is the mineral of greatest value to Brazil’s mining industry representing 78% of total mining exports; $16.5 billion of a $22.5 billion industry in 2008. Over-reliance upon the production and export of iron ore to China the overwhelming driver of demand for Brazil’s iron ore
Mining flotation chemicals aid or inhibit the floatation of minerals out from the rock surface with help of certain chemicals such as collectors frothers flocculants etc. ... has also benefitted from the use of low VOC and environment friendly product types and growing demand in extraction of phosphate-based mineral and iron ore.

Phosphate is a minor but important constituent of iron ores and is especially undesirable in the production of steel where it is considered a penalty element and is therefore tightly controlled. Iron ore quality must be determined at source which means that deleterious elements must be accurately determined as an ongoing process.
