New R1bn manganese furnace signals beneficiation support – BHP Billiton

Engineering News 6 March 2013.

MEYERTON (miningweekly.com) – South Africa’s Minerals Minister, Susan Shabangu, on Wednesday opened the largest operating furnace of its kind in the world at Samancor Manganese’s Metalloys smelter in Meyerton, allowing mining giant BHP Billiton to beneficiate close to 30% of the manganese ore it mines locally and demonstrate its support for increasing value addition and downstream job creation…

..The furnace uses improved technology, allowing the offgas that is emitted to be used for additional power generation, which increases electricity self-sufficiency on the site to 20% and reduces the electricity supply burden on South Africa’s hard-pressed State power utility Eskom…

Action in energy arena needed

Business Report, Liz McDaid, Robert Fischer, Yvette Abrahams 18 December 2012.

Once the brouhaha around who will lead the ANC for the next five years is out of the way, those at Mangaung this week have a bigger dilemma on their hands.

With rising unemployment, an ever widening gap between rich and poor, and mounting social unrest, the ANC is arguably in one of the toughest spots it has been in since coming to power. It has to act decisively to deliver on its promises of a better life for all or risk losing credibility.

One opportunity for decisive action lies in the energy sector, where many of these challenges converge. Key decisions here will have massive impacts on national debt, social equity and job creation in the years to come, to say nothing of environmental consequences.

Access to modern energy services is considered to be a key aspect for improved economic development and reducing inequality. The many economic and social benefits that accrue to humanity in general and the poor in particular, from access to electricity, for example, are covered by a vast body of respected research…

Jubilee to sell electricity to Eskom

Engineering News 17 October 2012.

JOHANNESBURG (miningweekly.com) – Aim- and JSE-listed Jubilee Platinum has received approval from the National Energy Regulator of South Africa to start selling electricity to national power generating company Eskom.

Sales of electricity are expected to start on October 26.

Jubilee currently has a 51% interest in power generating company Power Alt as previously announced has entered into a process of acquiring an additional 19% interest…

(Editor’s note: I wonder how much Eskom is paying for the power? Power Alt have an 18 year contract for the supply of Sasol gas for the 10 MW reciprocating gas engine of the power station.)

Richards Bay paper mill aims to add 47 MW of own generation by Nov 2013

Engineering News 17 August 2012.

Forest products group Mondi has announced plans to install a 47 MW steam turbine at its Richards Bay mill, in KwaZulu-Natal, which will further increase the facility’s power self-sufficiency and produce surplus electricity for input into the South African grid.

The plant is expected to begin operating in November 2013 and will materially bolster self-generation at the mill, which already stands at 86% – the mill invested in a 27 MW gas turbine in 2006, as well as in a heat recovery programme…
