11.17.1 Process Description1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.Figure 2.1: Flow diagram of production department.

Cement Manufacturing Process Phases Flow Chart Cement
Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.Figure 1 and Table 2 describe the flow-diagram and process parameters of the pilot plant.

Analysis of material flow and consumption in cement production process
The mined limestone is fed to primary and secondary crushers where its size is reduced to 25 mm. In recent times, a tertiary crusher has been used to further reduce the inlet size to the mill. The units within the system operate in a steady state condition and steady flow process. 2) Fig. 10 shows the material flow diagram of the cementThe sulfuric acid process is the dominant technology for lithium extraction from spodumene. However, this process generates huge quantities of waste residue and needs high-temperature pretreatment. The process can be optimized if other high-value elements are found in spodumene deposits, residual lithium can be recycled during Lithium Extraction from Spodumene by the Traditional Sulfuric
