Mar 26, 2020· Lithification is the process by which sediment turns into hardened rock. There are three ways in which lithification can occur. These processes are called compaction, recrystallization and cementation. Compaction is a process of lithification that works for finer particles only. Compaction occurs when particles such as clay minerals are compressed.
Electrolysis is a method of compound decomposition, which passes an electric current through an ionic compound and split it into elements. The basic electrolysis procedures: When the power source is turned on, the positive and negative ions in the compound are attracted to their oppositely charged electrodes.At the cathode positive ions receive electrons, and at the anode, negative ions lose ...

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
Methods / Types of Dressing of Stones. As said earlier, dressing of stone can be done both manually as well as mechanically. Manually, skilled stone-smiths can work wonders on the suitable type of stones with chisels and hammers and abrasives. Mechanically, machines can cut the stone to any desired size and shape. Their surfaces can be made extra smooth by polishing through machines.
