Canadian Federal Government Invests Millions in Mining Wastewater Treatment

As many mining operations use water on a large scale, in various processes, this produces wastewater that is highly concentrated in pollutants due to the contact between various minerals and the water. Mining pollutants can be caused by:

  • Water leaching, concentration and flotation
  • Wash water
  • Contaminants from gas scrubbers and refining
  • Flow process acids

Additionally, rain that penetrates mine tailings can cause hydrolysis, oxidation and washing, which produces wastewater that is highly contaminated. If this wastewater is discharged into the environment without being treated, it may contaminate the environment that surrounds the mines. With the harsh impact of wastewater pollution on the mining and ecology sectors, many governments…

China says US has 'weaponized' visas to target exchanges

Oct 27, 2020

BEIJING — China on Wednesday accused the U.S. of having "weaponized" the issuance of visas following the reported inability of a top Chinese space program official to obtain permission to travel to a key conference in Washington. Foreign Ministry spokeswoman Hua Chunying told reporters that the head of the Chinese delegation to the International Astronautical Congress wasn't able to obtain a visa following an Oct. 12 interview, making it difficult for Chinese representatives to attend important events at the meeting. Reports said the vice chairman of the China National Space Administration, Wu Yanhua, had planned to attend the congress. Hua...

Seoul police up security after rally at US envoy residence

Oct 27, 2020

SEOUL, South Korea — South Korean police said Saturday they beefed up security at the U.S. ambassador's residence in Seoul after a group of anti-American students used ladders to break into the compound. They were protesting demands by the Trump administration that South Korea pay more to help cover the costs of keeping U.S. troops in the country. Officials from three Seoul police stations didn't immediately say whether they will seek to formally arrest any of the 19 university students who were detained Friday afternoon at the residence of Ambassador Harry Harris. The Seoul Metropolitan Police agency said Saturday the...

Protests squeezing Hong Kong economy, tourism, leader says

Oct 27, 2020

HONG KONG — Hong Kong's economy is languishing after months of increasingly violent protests, the city's embattled leader Carrie Lam said Tuesday. Lam, addressing reporters after a long weekend of more turmoil, said tourism arrivals were down by half and that hotels and retailers were suffering. Hong Kong's third quarter economic data will definitely be "very bad", said Lam, the semi-autonomous territory's Beijing-backed chief executive said. Lam said she did not have the data with her. But empty streets and tourist attractions are evidence of the fallout from the protests that began in June over a now-shelved extradition bill that...

US priest who gave out gifts in Philippines accused of abuse

Oct 27, 2020

TALUSTUSAN, Philippines — The American priest's voice echoed over the phone line, his sharp Midwestern accent softened over the decades by a gentle Filipino lilt. On the other end, recording the call, was a young man battered by shame but anxious to get the priest to describe exactly what had happened in this little island village. "I should have known better than trying to just have a life," the priest said in the November 2018 call. "Happy days are gone. It's all over." But, the young man later told the Associated Press, those days were happy only for the priest....

In Japan, a court case highlights paternity leave issues

Oct 27, 2020

TOKYO — He sits in an office of a major Japanese sportswear maker but reports to no one. He is assigned odd tasks like translating into English the manual on company rules like policies on vacations and daily hours, though he has minimal foreign language skills. He was sidelined, he says, as retribution for taking paternity leaves after each of his two sons was born. Now he's the plaintiff in one of the first lawsuits in Japan over "pata-hara," or paternity harassment, as it is known here. The first hearing is scheduled for this week. His case is unusual in...
