Role of Concentration and Priorities in Effectiveness...

Role of Concentration and Priorities in Effectiveness Both the concentration and setting of priorities play a major role in an executive’s effectiveness. In fact, an effective executive does first things first and he does one thing at a time. The need of concentration is embedded both in the nature of the executive job as well as in him as a person. There are many apparent reasons for this. There are always more important contributions to be made than there is time available to make them. If someone analyses the richness of the important tasks to which the executive contributes and the time available with the executive for the tasks, then he comes up with an embarrassing situation which reveals a scarcity of time available for the work that really contributes. It is a fact that no matter how well the executive manages his time, the greater part of it is still not his own and hence, there is always a time deficit. The more an executive focuses on upward contribution, the more he needs fairly big continuous shares of his time. The more he switches from being busy for the achievement of the results, the more he has to make sustained efforts and these efforts require a fairly large quantity of time to bear fruit. And to ensure that this time which is really productive is available, the executive needs self-discipline and a very strong determination to say ‘No’. Similarly, the more the executive makes efforts at making strengths productive, the more he becomes conscious of the necessity to concentrate on the human strengths available to him on major opportunities. This is the only way to get results. But concentration is dictated also by the fact that most of the persons find it hard...

Low grade Iron Ore Beneficiation and the Process of Jigging Sep25

Low grade Iron Ore Beneficiation and the Process of Jigging...

Low grade Iron Ore Beneficiation and the Process of Jigging Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply. Hence, the scenario is steadily shifting towards the use of low grade iron ores and slimes which are stock piled in the mine’s sites for years. These dumped slimes also, in fact, falls in the category of low grade iron ore.  Also, some of the ores of iron have a complex mineralogical composition and do not respond to conventional beneficiation techniques. Modern beneficiation processes allow for effective and low cost upgrading of lump, fines and ultra-fines of such ores. Since the iron ores consist of several compositions, mineralogies, shapes, and sizes, so there is no ‘one size fits all’ approach to the beneficiation of iron ore. Most of the ‘run-of-mine’ (ROM) iron ore contain a large percentage of other materials which need to be removed through the process of beneficiation before the ore attains the specifications needed for its use. The extent of the beneficiation techniques employed depends on the level and nature of diluents and the form of distribution of the gangue and impurities in the ore structure. Liberation of ore is an essential step for making it responsive to the beneficiation techniques. For selection of appropriate techniques, it is necessary to carry out first the mineralogical assessment of the ore so as to get the insight into the ore and to know the gangue association, and grain size etc. There are several issues relating to categorization and beneficiation of low grade iron...
