Ball milling and ultrasonication were used to reduce the particle size and distribution. During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied. The milled particles were dispersed in xylene to disaggregate the clumps. Again, ultrasonication was done on milled samples in xylene. An investigation on the amplitude (80% and 90%), pulsation rate (5 s on and 5 s off, 8 s on and 4 s off) and time (15 min, 1 h and 4 h) of the ultrasonication process was done with respect to particle size distribution and the optimum conditions in our laboratory were determined. A particle size analyzer was used to characterize the nanoparticles based on the principles of laser diffraction and morphological studies

Special exemptions and tax reductions were negotiated for each project, and, as a result, the government will receive less in fiscal revenues from these projects than is typical in most other countries. Negotiations were hampered by the governments lack of capacity to use financial models to measure and understand the implications of fiscal incentives. The 2000 model mining agreement was originally envisaged as a means to supplement, not supersede, existing laws, including the mining law, but the final version of the 2002 mining law that emerged from parliament removed restrictions on subject matter, thus opening the way for the minister responsible for mines to exercise a great deal of control over the fiscal content of the agreements. Additionally, Mozambiques Council of Ministers had wide latitude with regard to mineral sector tax matters. All investors in large-scale mineral projects before 2007 (Mozal, Corridor Sands, Moma) negotiated agreements containing substantial fiscal incentives
