Russian news agencies report Uralkali, Russia's largest potash miner, is not planning to buy Belaruskali, a major Uralkali shareholder said on Friday. Last week it was speculated that the cash-strapped ex-Soviet republic Belarus is negotiating the sale of its most prized asset under the terms of a bail-out loan agreed with Russia. Responsible for one-third of the worlds potash fertiliser production, Belaruskali could have been worth as much as $20bn and a merger with Uralkali owned by billionaire Suleiman Kerimov would have created a group with annual production of 21m tonnes, dwarfing current number one Canada’s Potash Corp's 12m tonnes/year.

The troubled country, emerging from years of hyperinflation and political turmoil, is however barred from selling diamonds because of alleged human rights violations and has built up a stockpile worth $4bn–$5bn.

Commodities trader Glencore (GLEN.L: Quote) is not considering a bid for embattled miner ENRC, its chief executive said, dismissing reports of a takeover after it disappointed the market with its maiden frst-quarter results. Shares in the world's largest diversified commodity trader dropped 2 percent as weaker-than-expected results from its metals and mining trading unit held back its operating profit.
