New Delhi: German electronics equipment maker Blaupunkt on Saturday said it would introduce its new TV line-up comprising the premium 55-inch QLED 4K smart TV during Amazon Prime Day 2019 sale. The premium QLED 4K model would be available for Rs 64,999 during the sale, the company said in a statement. “With the introduction of QLED Series, we aim at embellishing the customers’ viewing experience by transforming the living room into an entertainment hub,” it added. The QLED TV would be available for Rs 69,999 after the Prime Day sale on other channels. The TV features over a billion shades and imagery with the company’s Quantum Dot Technology and 100 per cent colour volume. The device also comes with “Smart Air Mouse Remote” — which facilitates a user-friendly and hassle-free experience, and is voice-enabled as well.
BacTech Environmental Corp has been awarded the contract by the Mines Branch of the Manitoba Department of Innovation, Energy and Mines (Canada), to remediate a stockpile of arsenopyrite concentrate located in the community of Snow Lake. The contract is subject to negotiating a suitable agreement between BacTech and the Manitoba government. BacTech has proposed a “no cost to the taxpayer” approach to the clean up.The company will recover payable metals for its own account from the stockpile while treating the contained arsenic. BacTech’s bio-oxidation technology has been used successfully in the gold industry for many years to aid the extraction of gold from arsenical concentrates, while stabilising arsenic values into a benign form.BacTech’s interest in the project stems from test work completed in 2010 whereby bioleaching technology was determined to be well suited for the stabilisation of the high levels of arsenic in the stockpile.This will be the first commercial bioleach facility in North America. Ross Orr, President & CEO, said, “This is a major step forward for BacTech as we position ourselves as a leader in the field of tailings reclamation. It is a highly visible project whose success could lead to bioleaching playing a prominent role in future clean ups in North and South America.”The Snow Lake stockpile was created in the 1950s as a byproduct of gold production from the Nor Acme mine. Due to the refractory nature of the ore and its high arsenic levels, it was decided at that time to produce an arsenopyrite concentrate which was subjected to cyanidation to recover exposed gold values, leaving behind a residue which contained significant gold values that would be processed at a later date. Based on historic data provided by the Manitoba Mines Branch in the Request for Proposal, the stockpile is estimated at approximately 250,000 t with an average grade of some 9 g/t Au. The stockpile is 6 m to 10 m high and encompasses an area of about 19,500 m2.BacTech has engaged the services of Dr Barbara Sherriff, a recently retired professor from the University of Manitoba who has a 15-year history evaluating the stockpile. Dr Sherriff will oversee the drill program slated to begin on May 9. The program will obtain representative samples from some 30 holes to be drilled on the stockpile. These samples will be subjected to diagnostic and bioleach testing to determine the appropriate approach for treating the concentrate.Alexis Minerals Corp, the mine leaseholder, has granted BacTech access to the site so that samples can be obtained for test work. The bioleaching test work will be completed later this year. An environmental baseline study will begin shortly which will take approximately one year to complete.The anticipated life of the project, beginning with the onset of processing concentrates, will be approximately six to seven years. Engineering design for the plant and operations will be carried out concurrently with the work program described above. The current anticipated start date for the construction of the plant will be the summer of 2012.Conceptually, the plant may also have value in being capable of treating other refractory type gold values and waste in the region, and efforts to incorporate this concept may be made at the design stage. If the concept is incorporated as part of the project plan then, clearly, this adds additional value to the project in creating a regional bioleach facility for treating other materials.
