The main purpose of this study was to improve transdermal delivery of LP by encapsulating LP in niosomes. Niosomes loaded LPs were prepared by coacervation phase separation method using non-ionic surfactant (Span 60), labrasol, and cholesterol. The optimum formula obtained were Span 60, labrasol and cholesterol at the mole ratio of 6:1:4.

There are two further mineral deposits within the Svecofennian domain that deserve to be mentioned. The Korsnäs Pb-REE deposit in westernmost Finland (Fig. 2.2) was mined from 1961-1972 producing both Pb and REE. It occurs in ~1830 Ma, 20-m-thick carbonatite dike cutting Svecofennian mica gneisses (Isokangas, 1978).

Previous test work conducted on the B2 nickel ore by Jinchuan Group Limited (announced by Fox in August, 2006), produced a 4.9% nickel in concentrate. The recent upgrade was achieved by utilising a magnetic separation technique, which was not utilised in previous testwork done by the Jinchuan Group.

Nickel laterite ores, which comprise 73% of the world's proven nickel reserves (approximately 160 million tons), are the dominant source of nickel [ 2 ]. However, only 42% of the world's production of nickel comes from nickel laterite ores [ 3 ]. The high-grade nickel-containing sulfide ores are becoming depleted and also more difficult to mine.

Jun 2, 2021There is no simple separation technique for nickel laterites. The rock must be completely molten or dissolved to enable nickel extraction. As a result, laterite projects require large economies of scale at higher capital costs to be viable. They are also generally much higher cash-cost producers than sulfide operations.
