1. Introduction. Limestone is a sedimentary rock composed mainly of calcium carbonate in the form of the calcite mineral and represents a significant share of the Uruguayan mineral resources (National Department of Mining and Geology, 1987).The Queguay Formation, located in the northwest zone of the country, features a non-metamorphosed limestone …
Answer: a Explanation: Much of the locally available limestone has too high a silica and iron content for direct use in cement manufacture. These undesirable constituents can be removed by ore dressing or beneficiation methods which are based on fluid mechanics and adsorption.
The below Cement Rock Beneficiation Process flowsheet represents a simplified flow diagram of a cement plant in which beneficiation of raw materials is employed. Using a crude feed of limestone and/or clay, the flowsheet produces raw clay by multi-stage cycloning, and "Sub-A" Flotation upgrades the impure limestone.
Concentrating the needed minerals in the mined material is known as the beneficiation process. Sometime, the beneficiation at the primary level can be done during the mining. …
