The installation of cement industries especially in South Punjab/Saraikistan Province due to close occurrences of resources should develop the area and increase the export. The Koh Sulaiman regions of South Punjab (Saraikistan) have huge gypsum deposits which deserve for further exploitation. Pakistan is agricultural country and fertility of cultivated lands is vital. Fertilizer resources like phosphate deposits are moderate but the deposits of phosphate and potash bearing rocks are very vast and need their further explorations and exploitation in the Indus Basin. Pakistan has very large construction, dimension and decor stone deposits like limestone, marble, dolomite and igneous rocks like granite, dolerite, serpentine, etc. which needs further exploitation for the development of the areas and increase export. Pakistan is spending a lot of earnings for importing glass, glass wares, pottery, clay, etc. while Pakistan has these resources which needs exploitation of own resources. The best structures and geotectonic elements like the Northern and Western Indus Sutures and Karakoram Suture and Indus placers which are rich in gemstones and jewelry resources. To increase gems and jewelry export, these industries requires reduction in gemstones smuggling and encouragement for gem appraisal and jewelry industry at high level for value addition. In short, Pakistan is rich in natural resources but poor in development. Try should be made to develop and export the own mineral commodities like cement, gypsum, marble, gemstones and jewelry.展开更多

They permit, for example, to do the local surfacing without essential deformations of rather thin jewelry elements, including a big growth a rise or layer of metal which exceeds it thickness in 2~8 times at the space with the approximately the same sizes. Such opportunities are based on the various possibilities of the joint producing-with different participation of metal parts and filler material. It may be added as a standard paste, wire, strip, etc. An operator can easy choose-where it is reasonable to apply only welding or brazing process as well as their combinations-due to his qualification, the concrete jewelry good design, needed accuracy of the given joint adjustment and, of course, the operators fantasy. At the same time he has excellentchances to repair the spoiled jewelry good or its element. All these processes are very easy for realization and theymay be even made by beginners and not only in jewelry, but also forrepairing of copper tubes, brass heat exchangers, various bronze goods, in dental purposes.展开更多
