The eight-day event, due to take place from October 12 to 19, will be hosted by the Curl Aberdeen sports complex.

The appointment comes a year after the same venue staged the 2018 World Junior Curling Championships.

This will also be one of two World Curling Championships held in Scotland in the 2019-2020 season with the 2020 event for senior men scheduled to be played at the Emirates Arena in Glasgow from March 28 to April 5.

"Curl Aberdeen put on an excellent World Juniors in 2018 and I am delighted they’re eager to deliver another major international curling event," Kate Caithness, the Scottish President of the World Curling Federation (WCF), said.

"From the experience we had in Aberdeen in 2018, I am in no doubt this will be another memorable World Mixed Championship."

The World Mixed Curling Championship is an open entry event for the WCF’s 61 Member Associations.

Mixed curling consists of two female and two male athletes - with no alternate - and follows the same rules as "traditional" curling with the exception that games will be played up to a maximum of eight ends.

"We’re really pleased to be hosting the World Mixed after the success of the World Juniors last year," Curl Aberdeen manager Tom Brewster, who helped Great Britain to men’s curling Olympic silver medal at Sochi 2014, said.

"It will be great to see the vast number of countries coming to compete - it will be a lot of fun.

"The venue itself and Aberdeen as a destination are perfectly set up for this sort of event."

Hosts Canada beat Spain in the final of the 2018 World Mixed Curling Championship in Kelowna, winning the country's first title.
