Cel From the experimental work and the techno-economical assessment carried out within the present research programme, the following conclusion were derived: In Northern Hellas, there exist estanded deposits of "olivine" sources of comparable quality to other "olivine" sources in market. Since the above deposits are connected to existing manganese and chromite mining activities, from which they derive as by-products, there are not charged with quarrying costs. The cost estimation for the production of Greek olivine sand is comparatively low compared to the FOB prices of the other olivine products in market. Since the cost of olivine sand remains higher that the cost of silica sand the trade perspective of the Greek product will depend on growing demand of olivine in terms of increasing consumption and enhancing development in new application areas national environmental measures restricting the use of quartz in the metalliferous sector due to health concerns. The use of Greek olivine sand instead of silica sand, as foundry material is advantageous in the case of casting manganese steels and cast irons, where the casting temperature is relatively low. In the case of casting other steel grades (high alloy low alloy, carbon steels) silica sand gave better results. The practice showed that the use of low cost binders, like bentonite, does not give to the olivine sand good performance during casting. The olivine process which has been invented to neutralize industrial waste acids with olivine is an environmentally and economically attractive procedure. The process can be further developed as new industrial method to produce precipitated silica, synthetic clays, synthetic zeolites and/or high purity magnesium-sulphate products. Two important applications of the produced silica are possible. It can be used as a high-quality product to replace silicas which are presently on the market. In this case the silica would have to be quite pure and will have to have the required specifications further research is needed to develop this spinoff of the project. The same applies for the use of this silica to produce synthetic clays and zeolites. Another application is the use of silica in concrete or cement. Applied research in conjunction with end-users is needed to produce the specific qualities needed by these industries. If the price of the silica, magnesium-sulphate solution and/or magnetic ferrites can be realized the process can provide a positive cash flow, which in the case of a waste treatment process is quite unique. If no price for the end-products can be made the costs of neutralization per tonne of acid are estimated to be fl. 80/tonne which is still competitive with prices which are being paid by the industry for the treatment of their waste acids (fl. 100/tonne or higher)Abundant, large in size, dunite bodies hosted in ophiolite complexes occur in Northern Greece. Various existing mining activities exploit mineral deposits (e.g. chromite and magnesite) that are hosted in dunite. Therefore, large amounts of dunite by-product can be recycled for "olivine" production. This olivine production aims in the preparation of a material suitable for the substitution of the environmental hazardous quartz sand in the foundries in Southern Europe and for the neutralization of industrial waste acids. The working plan consists of the following four main tasks :a) Exploration studies for the location of the most promising dunite bodiesb) Ore processing study including crushing, grinding and scrubbling tests. Calcination tests on beneficiated samples.c) Industrial application trials including casting of steel. Application of several binders and resin-bonded processes.d) Tests on the suitability of olivine for the neutralization of industrial waste acids.e) Technical and economical justification of the results.
