· Abstract. The seeds of deep-sea mining were sown during the post-war boom. The massive use of raw materials and the wholescale destruction of both property and material during that war created a demand for raw materials that some thought could not be met from conventional sources. Amongst these was a group of University of California Professors ...

· § Iltani is focussed on the discovery and supply of the raw materials the world needs to realise a clean energy future. Australian based and with a fundamentals-driven bias to copper, shareholder value creation through astute business growth – at the drill bit and in the boardroom – is at the core of our deeply experienced team
This article reports a simple and cost-effective method to prepare ultrafine nanocrystalline MgO/MgAl2O4 spinel (M-MA) powders from industrial wastes arising from aluminium and magnesium scraps. M ...
The effect of the particle size on the raw materials over the density, the open porosity and the breakage resistance of the proppants was evaluated. The phase composition and the structure of the proppants due to the milling process were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and pore size distribution by ...

· Black ceramic pigments were prepared from industrial wastes as raw materials, namely, Cr/Ni-rich sludge generated from Cr/Ni plating and Fe-rich galvanizing sludge generated during steel wiredrawing. The pigment was based on the chrome–iron–nickel black spinel (Ni,Fe) (Fe,Cr) 2 O 4 catalogued as 13-50-9 in the DCMA classification and ...
Improved Production Economics for Cement Manufacturers. Primary aluminium smelting uses: large amounts of carbon. silica refractory materials. alumina as raw material. sodium and fluoride chemical compounds as flux. The spent potlining waste material from aluminium smelting has all of these materials inextricably mixed together.
· Using the fCaO values of the sintered samples, the burnability capacity (BC) of the raw mix can be estimated from Eqs., . (1) C = fCaO 1000 ° C +2 fCaO 1100 ° C +2 fCaO 1200 ° C +3 fCaO 1300 ° C +4 fCaO 1350 ° C +4 fCaO 1400 ° C +2 fCaO 1450 ° C (2) BC =600/ C The resulted values of BC are given in Table 2. As can be seen (), the effect of the added mineral …
