in their chemistry, there is a poor bond between silica and the host stone. Thus, the silica gel that is deposited may fill the pores of the stone but does not necessarily improve cohesion. Figure 2 Diagram showing the equipment and method for
Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist. Commercially, the term limestone includes dolomite, dolomitic limestone, oolitic limestone,
The bond work index of granite is expected to be the highest due to the ore being mostly composed of the hard mineral quartz. Bond Work index values of granite presented in literature range from around 14-15. Limestone is theorized to have a Bond Work index with a value of around 11. This is due to the main presence of calcite, a softer mineral.
What is Limestone Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
The Bonds standard ball mill is used to determine the work index value of differ ent samples.
