Fabio Schvartsman and several other executives asked to be removed after prosecutors called for their dismissal.

At least 122 people are still missing more than a month after the accident at the dam, which collected waste from an iron ore mine in Minas Gerais state.

Vale is the world's biggest producer of iron ore.

The company described the executives' removal as temporary, but did not say how long it would last.

The announcement was made late on Saturday, during the Brazilian carnival weekend. The main Sao Paulo stock exchange will be closed on Monday and Tuesday.

The mining disaster was the second in the region since 2015, when a nearby dam co-owned by Vale collapsed.

Brazilian authorities were severely criticised for being too slow and complacent over that accident. No-one has yet been imprisoned.

Vale said Eduardo Bartolomeo, executive director of base metals, had been appointed as the new head of the company.

The other executives stepping down were Vale's head of ferrous minerals and coal, Peter Poppinga, planning director Lúcio Flávio Cavalli and Silmar Magalhães Silva, the head of a geographic division.

Brazil's dam disaster: Looking for bodies, looking for answers
A German consultancy firm, Tüv Süd, carried out an audit of the Feijão dam last September which found the dam met legal requirements.

But an internal report seen by the Reuters news agency said the Brazilian mining company knew the dam was at risk as it was told the site breached guidelines months before it collapsed on 25 January.

Vale said the report was misleading as there was no evidence of imminent risk.

However, the Vale chief had little choice but to resign after federal prosecutors recommended that he and three other senior executives be temporarily removed.

Mr Schvartsman defended his handling of the accident as "absolutely appropriate", but admitted that his presence had become an "inconvenience" for the company.

It is still not known what caused the collapse at Brumadinho, but experts believe liquefaction was to blame.

Liquefaction is a process whereby a solid material such as sand loses strength and behaves more like a liquid.

Germany, along with some other major EU economies, is set to have a much higher share of electric vehicles among its new registrations than the average rate across the bloc, he added.

Europe needs to boost electric mobility because without it, goals for the reduction of carbon dioxide emissions in the EU cannot be achieved by 2030, according to Mattes. For this purpose, the appropriate regulatory conditions must be met. Massive expansion of the charging infrastructure is also required, along with more offerings for e-vehicle buyers.

At the same time, Berlin expects a significant decline in domestic car production this year due to a slowing economy, trade risks linked to US tariffs, as well as the expansion of plants in the US, Mexico and China, the VDA chief warned. German plants are expected to produce 4.8 million passenger vehicles this year, which is around five percent fewer than in 2018.

Noting that Australia is one of most important third neighbors and largest investors of Mongolia, which consistently supports democracy and reforms in our country, Minister D. Tsogtbaatar expressed gratitude for the valuable contribution of Australian government for training Mongolian public servants.

During the meeting, the parties agreed on the possibility of expanding bilateral relations in all areas, especially the continuation of experience exchange in developing accountable mining and good governance.

Ambassador David Vosen expressed his commitment to pay more attention on increasing reciprocal high-level visits between two countries.

Besides the issues of bilateral relations, the parties also exchanged views on a wide range of issues of mutual interest, such as international and regional cooperation and diversifying economy and attracting investment.

While recent merger and acquisition transactions have raised concerns about the future of Canada's mining sector, domestic firms remain optimistic about growth opportunities. Canadian stock exchanges are the global leader in mining financings, and Canada continues to be a global hub for mining finance, KPMG reports.

Heather Cheeseman, partner, energy and natural resources, KPMG Canada, believes the industry is at a “crossroads” in Canada.

"Innovation and new technologies are rapidly reshaping the sector, while environmental and social expectations continue to grow. At the same time, we are seeing consolidation in the industry as companies look to find synergies and drive down costs,” Cheeseman said in a statement.

Cheeseman added that despite many factors disrupting the industry, miners remain confident that they will be able to continue to grow their companies.

"While organic growth will always be the main driver, Canadian executives are increasingly seeing mergers and acquisitions and technology as the keys to expansions," she said.

The report finds that mining executives increasingly believe innovation and advances in technology will reshape the industry, with 73% seeing this as more of an opportunity to their companies than a threat.

Of the surveyed, 66% are confident or very confident in their ability to grow in 2019, 73% expect to grow organically, 40% plan to grow via mergers and acquisitions and 29% plan to use innovation and technological transformation to grow.

"There has been some concern about the future of the sector in Canada given recent deals that could shift control out of the country," Cheeseman said. "While I think the conditions driving change will only grow in 2019, I expect the Canadian mining sector to remain healthy. I expect a number of Canadian players to go on offense and be buyers this year."

It is expected to drive 500 kilometers (275 miles) on a single charge thanks to a 78-kilowatt-hour battery (72 kWh for the Chinese market) integrated into the floor.

Production of the electric car in both right and left-hand-drive versions is to start in 2020 in southeast China, according to the automaker. The initial launch markets include China, the US, Canada, and some European countries, and the company vowed to consider further expansion.

“Polestar 2 is our first fully electric car and first volume model,” Polestar’s chief executive officer, Thomas Ingenlath, said in statement on Wednesday.

The range of the new Tesla rival almost equals the long-range version of the Model 3, which is 310 miles, and the price will also be close to the one Elon Musk’s company offers. The car will be priced from €39,900 ($45,500) up to €59,900 ($68,000).

However, during the first year of production it will sell only the limited edition launch model for $63,000, and federal and state incentives can drop the price by $7,500.

Polestar 2 is one of the first cars in the world to feature an infotainment system powered by Android which allows drivers to use Google Assistant, Google Maps and other apps from the Google Play Store.

The company, jointly owned by Volvo Car Group and Zhejiang Geely Holding, launched its first car – the Polestar 1 hybrid performance coupe – in 2017. It also plans to start production of a fully electric SUV which will be Polestar 3.

Other major auto companies have already joined the race to win the hearts of eco-friendly customers, with Jaguar launching its I-Pace fully-electric model and Porsche preparing to start sales of its first fully-electric sports car, Taycan.

Last year, Volkswagen-owned premium brand Audi unveiled battery-powered crossover E-Tron.
