  • Phosphate Industry an overview ScienceDirect Topics

    When phosphate rock, phosphorus concentrate, and fluxes are smelted in an electric arc furnace under temperatures of 1400–1500 °C (2552–2732 °F), molten slag is formed and tapped out from the furnace and goes through an air-cooling or water quenching process. The elemental phosphorus is separated from the impurities during the slagging

  • Processing Phosphates for Use in the Fertilizer Industry

    Map & Dap Fertilizer ProductionAn Alternative Approach to Map GranulationAdditional Phosphatic FertilizersConclusionOnce phosphate rock has been mined, the actual phosphate ore is beneficiated to separate it from the unwanted materials. This is carried out via a wet process, the resulting material of which must first be dried. This is typically carried out in a rotary dryer, an industrial drying system ideal for processing phosphate ore, because of its heavy-duty build and high capacity capabilities. The dried phosphate ore is then most commonly pr在feeco上查看更多信息预计阅读时间:4 分钟
