Dust generation in the crushing process is a very important aspect of operation. Control of the dust by collection and washing of equipment on a periodic basis is very important to reduce the risks of fire in the processing of sponge. Care has to be taken to avoid working on equipment when dust present as titanium metal fires are difficult to extinguish; a class D extinguisher or rock salt are used to suppress the first. The high temperature of the fire and the low melting point of iron-titanium eutectic can result in melting of equipment, supports or piping in these plants if a fire does occur

The East Germans, on the basis of their understanding of the importance of lithotype in the briquetting process, have developed a Quantitative Micro-petrographic Analysis (QMA) classification system (see Chapter 2) to predict the suitability of brown coals for briquetting (Sontag and Suss, 1973). According to this classification the more highly gelified coals, i.e. coals with high levels of dark and medium dark lithotypes, are less satisfactory for briquetting. Experience with briquetting Yallourn coals confirms that the darker lithotypes are the ones most likely to cause quality problems in briquetting and subsequent carbonisation

Figure 9.6. Photographs taken from KISR-EBRC/NAM Lab, Kuwait, show (A) the vial and milling media (balls) and (B) the setup performed to charge the vial with 50bar of hydrogen gas. The photograph in (C) presents the complete setup of GST (supplied by Evico-magnetic, Germany) system prior to start the RBM experiment for preparing of MgH2 powders, using Planetary Ball Mill P400 (provided by Retsch, Germany). GST system allows us to monitor the progress of RBM process, as indexed by temperature and pressure versus milling time (D)

A Porphyry Copper Deposit derives its name from a porphyritic stock located at the center of the material deposit. A stock results from a cylindrical mass of magma, which moves up through the Earths crust underneath a strato-volcano and cools. In a porphyritic rock, some of the minerals are very large crystals (up to 10 cm in length) and the rest are microscopic. Generally we find that the upper parts of the strato-volcano have been eroded away. The surrounding country rock, which has been intruded by the stock, is often metamorphosed by heat and pressure. During this metamorphism, sulphide minerals form in the rocks surrounding the stock. Heat and pressure causes pre-existing rocks to be altered into a new type of rock. An enriched mineral blanket or oxidized zone will then form near the surface of these deposits
