Subject The outlook for copper prices. Significance Having seen prices halve over five years, the copper market has stabilised since the fourth quarter of 2016. The long bear market forced the industry to cut exploration and capital reserves, and demand rebounded in 2016, growing by 1.8%. This year the market has started to tighten as there have been supply disruptions. Impacts Chile’s output could rise in coming years as the government will inject 975 million dollars to bolster state-owned Codelco’s growth. In six years, Rio Tinto and Chinalco found no copper in China and have stopped looking, so China will remain the world’s largest importer. Chile’s miners, reliant on costly coal and gas, are reviewing bids from wind and solar power producers, which may dramatically cut costs. To increase its stake in two Congolese mines, Glencore spent more than 500 million dollars to buy out Israeli financier Dan Gertler.

Weak Dollar

Subject Copper market outlook. Significance The combination of solid Chinese growth and the weak dollar drove the copper price 32% higher in 2017 and the metal has held on to its gains this year, oscillating around 7,000 dollars per tonne. Global consumption has been falling in recent months, and major customers have been paying lower premiums over benchmark prices to secure long-term contracts. This downward pressure on the price has been offset by supply concerns as the leading mines struggle to replace reserves. This leads miners towards lower grades, where they must process higher volumes of material, raising costs. Impacts Adding to near-term supply constraints, First Quantum will expand its Cobre Panama project by 15% but delay initial output to after 2018. Boosting supply, Peru is set to allow the Tia Maria project, recognising Southern Copper’s efforts to solve its legal dispute. Rio Tinto will negotiate a tax settlement with Mongolia after the company was hit with a 155-million-dollar bill for its Oyu Tolgoi mine.

Subject Simandou corruption allegations. Significance In October 2016, Rio Tinto announced it would sell its 46.6% stake in the Simandou iron ore project to China's Chinalco for between 1.1-1.3 billion dollars, giving Chinalco control of some 87% of Simandou. Once fully operational, Guinea's Simandou mine should account for 7% of the world's annual iron ore output. Notwithstanding its promise, the Simandou mine has been hampered by persistent allegations of public corruption, which culminated in the arrest of Beny Steinmetz, head of BSG Resources and Israel's richest man, on December 19. Impacts Chinalco will move quickly to begin production at Simandou, which will entail a massive infrastructure campaign. New corruption revelations could undermine Conde's reputation as a reformer and prompt popular unrest. The Fulani ethnic group will mobilise ahead of the 2020 presidential elections and protest if Conde attempts to secure a third term.

Objetivou-se, com esta pesquisa, analisar a qualidade do tratamento preservativo da madeira juvenil de Eucalyptus camaldulensis Dehnh. e verificar a influência da inversão das peças na solução preservativa, na distribuição, na penetração e na retenção do CCB, ao longo das peças tratadas pelo método de substituição de seiva. Árvores de Eucalyptus camaldulensis foram coletadas na Zona Rural do Município de Rio Tinto - PB, de um povoamento com quatro anos. No povoamento foram escolhidas, aleatoriamente, cinco árvores, sendo três de maior diâmetro. Para o tratamento da madeira, empregou-se o método de substituição de seiva por transpiração radial utilizando-se uma solução de 2% de ingredientes ativos de borato de cobre cromatado (CCB) e comparou-se o efeito da inversão das peças na solução preservativa. A distribuição, a penetração e a retenção foram melhores nas peças invertidas, quando comparadas àquelas não-invertidas na solução preservativa.

The great pyrites masses of the Sierra Morena, of which those worked at Rio Tinto are by far the most extensive, may be briefly described as contact deposits, which differ from such as are ordinarily met with only in size; and from ordinary fissure veins only in the circumstance that the cavities in which the minerals occur are bounded by dissimilar rocks.
