·Ore deposit is the gathering of ore where ore is defined as a rock or sediment which contains sufficiently high levels of minerals that can be profitably extracted
Media Attributions; Metal deposits are mined in a variety of different ways depending on their depth shape size and grade Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open pit mine methods Figure in Section Creating a giant hole in the ground is generally cheaper than making an underground
·In open pit mines the blast operation should be effectively optimized leading to minimization of production costs through the application of specific technical specifications However there is inadequate information in the literature to link blasting to comminution stages To this end the effective parameters for the performance of mining unit operations were
TEXT BOOKS of ore dressing are frequently little more than extracts from makers catalogues The volume by Prof Simons is of a different character It gives the usual descriptions of plant but enters more fully into the principles of the processes of separation and deals quantitatively with the theoretical and practical limits of concentration and with the theory of grinding It is

·An intelligent integrated method is proposed for optimizing the head grade and dressing grade in the mining and ore dressing management of metal mines beginning with the establishment of a nonlinear constrained optimization model with the objective function of economic benefit two constraints comprising of the resource utilization rate and the output of
·Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping and often clean ore can be obtained only by leaving some ore in the mine In open stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall
·In addition the identification and control of the factors that influence the technical condition of the slopes must represent a permanent concern throughout the life of the open pit
3 ·Dense medium separation DMS or heavy media separation is a pre concentration technique used to reject gangue minerals before grinding DMS exploits the difference in specific gravity between the target and gangue minerals and is also used in the separation of spodumene from other gangue specific gravity of spodumene is between and ; this
·Tin ore is one of the important strategic mineral resources tin and tin alloys have been widely used in modern national defense industry cutting edge science and technology and also in our daily life The development of tin ore beneficiation The beneficiation method of tin ore is determined by its own characteristics Because the density of […]
