Dear Readers in Bangladesh, we wish you a happy joyous Eid ul Azha.
We endeavor to bring you a positive insight into our developments, aspirations and plans through these newsletters..
Recently we have relinquished our river exploration licenses after a comparative study showing far better prospects within our original areas of focus.
We have been re-analyzing data collected during our first five years of extensive exploration conducted from 2007 near Teknaf. This areas and further south shows the most competitive valuable heavy mineral assemblage for success on the world-stage. Over the next few months we intend to focus on development of bulk testing and further mapping of an initial pilot plant proposal.
Premier minerals limited hopes for positive discussion about our mining lease applications and exploration licenses with the Government of Bangladesh in order to invigorate investment towards a sustainable and successful future this industry in Bangladesh.
Every quarter we bring you an update of the general market conditions of popular minerals that can be derived from mineral sands. The above graph indicates market conditions for the raw material we can process from the sands of Bangladesh.
The global titanium dioxide pigment industry continued to show signs of improvement. Recent feedback from China suggests that pigment demand had improved. Some pick-up particularly in Zircon has been indicated.Variable Demand
Iluka, has signed a joint development and intellectual property agreement with Vale S.A for evaluation of titanium-bearing minerals located at Tapira in Minas Gerais State, Brazil. Phase 1 of the Agreement includes geological, technical evaluations, market assessment and pilot plant design. Recently Iluka has also made an offers to buy Irish company Kenmare Resources, whose main asset is the Moma heavy mineral sands mine in Nampula, Mozambique
Mozambique also has good news for Savannah Resources which has announced it has identified five significant heavy mineral sands zones at its Jangamo deposit after a 3990 metre drilling program showed excellent results.
In Australia Cristal Mining's secured federal government approval for its $200 million Atlas-Campaspe project in south west New South Wales. The state government expects Cristal to contribute to road maintenance costs and the project will require new rail infrastructure to be built.
ASX-listed Junior Gunson Resources has moved to increase its mineral sands land-holding in Tanzania in a A$2.5-million acquisition, which includes Strandline Resource’s large license package within the highly prospective corridor in Tanzania which is still subject to shareholder approval.
Each month Premier Minerals features information presented in an internal article this time we have chosen to feature the typical mining processes. This operation in Florida contains an average heavy mineral content of 4 percent and requires removal of topsoil and land regeneration.
Prior to mining the trees and vegetation are harvested by normal silvicultural practices. One foot of topsoil is removed and stockpiled along the edge of the mine for later use in reclamation. The topsoil storage piles are also used to contain sediment and storm water within the project limits.
In the suction dredging method, an electrically powered suction dredge floats within a 15- to 20-acre man-made pond. At one end of the pond, the dredge draws in overburden, ore and water and transfers the mixture to a floating wet mill. Vibrating screens block out roots and other large objects. Spiral centrifuges are then used to concentrate and separate the heavy mineral sands from the lighter clays and quartz sands. The now 80 percent heavy mineral concentrate is then pumped to a stock pile area before being transported to a plant for further processing. The tailings of clays and quartz sand is discharged back into the pond behind the suction dredge. As the dredge moves forward, the area behind the dredge is recontoured, covered with topsoil, and re-vegetated to meet reclamation standards.
Auxiliary mining is used in locations that are not suitable for suction dredging. The overburden is removed with heavy earth moving equipment and stock piled for later use in reclamation. The ore body is then loaded on to trucks and hauled to an area in front of the suction dredge. The suction dredge than processes this material as described above. Tailings from the suction dredge are pumped back into the auxiliary area to back fill the mined out pits. The auxiliary areas are then backed filled with overburden, recontoured, covered with topsoil, and re-vegetated to meet reclamation standards.
