Advanced Techniques of Saponite Recovery from Diamond Processing Plant Water and Areas of Saponite Application

Methods of cleaning and processing of saponite-containing water from diamond processing plants in the Arkhangelsk region, Russia, are discussed. The advantages of electrochemical separation of saponite from process water enabling to change its structural-texture, physico-chemical and mechanical properties are demonstrated. Possible areas of saponite and modified-saponite products application are considered.

Recycling Prospects for Saponite-Containing Water at Diamond Processing Plants in Arkhangelsk Region, Russia

The analysis of methods of cleaning and processing of saponite-bearing technogenic waters of diamond mining enterprises of the Arkhangelsk region is carried out. The perspective of the electrochemical separation method for extracting saponite from man-caused waters, providing a targeted change in its structural-texture, physico-chemical and mechanical properties, is shown. The possible directions of realization of saponite and products of its modification in various branches of industry are considered.

The Research into the Effect of Conditions of Combined Electric Powered Diamond Processing on Cutting Power

The paper presents results of the investigation into efficiency of high-tensile composite materials grinding with metal bonded diamond abrasive tools, as well as it demonstrates the necessity to stabilize diamond disks cutting properties in order to reduce cutting power, since it is one of important economic indicators of processing. The comparative analysis of preliminary studies of various diamond processing methods reveals that the minimal cutting power is observed when using the combined method of electric powered diamond processing which includes electrochemical grinding and simultaneous continuous electrochemical dressing of the grinding disk surface. Further research into the suggested method reveals relevant mathematical dependences of metal-bonded diamond disks cutting power and electric modes. The analysis of the results shows that combining of hard-alloy surface electrochemical dissolution and electrochemical dressing of the disk surface facilitates mechanical cutting with high effectiveness and little effort. This leads to substantial reduction of cutting power as compared with other methods. The reasonable electric modes are discovered which provide the minimal cutting power without reducing efficiency of the process and quality of finished product.

Global Recession and Diamond Industry Workers: A Socio Economic Perspective

<p>The recent globalization recession (2007-08) and its effect is all pervasive, the only 1 2 3 difference is of magnitude. Gems and Jewelry is of the largest contributor in India’s total export. Out of this total export of India diamond contributes more than 12 per cent. Gujarat is the one of the biggest player in diamond processing (cutting and polishing) and contributes about 72 per cent of the total exports of India. As diamond industry is mainly export based industry, during recession it adversely gets affected. This paper is an attempt to evaluate the effect of the global slowdown on the cutting and polishing worker. The paper is a case study of diamond industry workers of Surat based on the primary and secondary data that has been collected from 100 diamond cutting and polishing workers of the diamond industry located in Surat of Gujarat. The paper comes up with the conclusion that the recent recession adversely affected the socio-economic condition of the diamond worker and the scheme of social and economic benefits to the effected people fails miserably to support.</p><p><strong>Economic Literature,</strong> Vol. XI (47-53), June 2013 </p>
