rate and with the current plant setup temperature is the only effective variable to change. The results of this study led to a reassessment of the HAL circuit, redesign and implementation of an upgrade whereby iron is effectively leached and subsequently removed from solution.

pted in comparison with annual plants. In our work we evaluate effects of natural (dihydroquer cetin, Zircon) and synthetic growth stimulators (Melafen, Fumar, EpinExtra) on rooting and ac climatization of common ash (Fraxinus excelsior. L.) microplants. The % % Zircon and 10 − 5 % Melafen enhanced . in vitro. rooting by 29%

The fused material was produced by mixing NaOH/zircon at a wt. ratio of (mole ratio 9) at 973° K for 15 min. Conditioning was done by water washing, drying, grinding and sieving. The optimum conditions for dissolution of Zr(IV) were leaching by 4 M HCl under reflux for only 5 min with a solid to liquid ratio of :10 w(g)/v(mL).

Zircon comes last in the Alphabets of gemstone but has the brightest sparkle. Zircon has a wide range of colors including white, blue, yellow, orange, brown, rose and green. It is a gemstone with great ancient history and is a natural, magnificent and underrated gemstone. Blue Zircon is the most demanding Zircon also known as Starlite.

Zircon (pronounced ZURconn) is a species that would undoubtedly be little known to the modern jeweler, if heat treatment were not used to convert the rather dull, natural stones into colors that are virtually unknown in nature. To be sure, one occasionally sees yellowbrown, yellowgreen and cloudy darkgreen stones that are probably untreated.

The processing sequence for the recovery of gold, ilmenite, and zircon from the Moclips Beach sample is shown in figure 2. This sample contained more ilmenite and zircon per ton of sand than any of the other samples obtained from the sand and gravel plants. Analyses of products and distribution of major constituents are shown in table 9.
