The International Olympic Committee suspended the Russian Olympic Committee a year ago in connection with a massive doping scheme at the 2014 Sochi Games but allowed 168 athletes to compete in neutral uniforms and without the national flag.
On Thursday, CAS disqualified Krushelnitsky's results from the Olympics, withdrew his credential and referred his doping case to the worldwide curling federation to determine a suspension from competition.
The athlete, who won the medal with his wife, had accepted a provisional suspension beyond the period of the Games.
The IOC is also considering what IOC athletes commission chairwoman Angela Ruggiero called "a wide range" of opinions among Olympic athletes both for and against Russia's reinstatement.
"This incident has cast a shadow over our sport and the unbelievable mixed doubles curling competition that had its debut here at the Olympic Winter Games Pyeongchang 2018", said a statement from the WCF.
Pyeongchang: The International Olympic Committee on Wednesday told its longest-serving member, Dick Pound, he was free to leave the organisation after the Canadian labelled fellow members "old farts" for not being tougher on Russian Federation over doping.
On Tuesday, the Olympic Athletes from Russia (OAR) delegation said Krushelnitsky had tested positive for prohibited substance meldonium in his doping sample B.

"Yeah, I'm sure the world really wants to know my thoughts on the doping scandal", Roberge said, chuckling.
It is partly for this reason some of Krushelnitckii's fellow curlers expressed surprise at the failed test for meldonium, a drug believed to improve athletic performance by boosting blood flow.
The timing couldn't be worse for Russian Federation, as Krushelnitsky's medal officially being stripped comes just two days prior to International Olympic Committee meeting to decide whether to reinstate Russian Federation and formally allowing its flag to fly at the Closing Ceremony.
"Unfortunately we have to part with the Olympic bronze medal", he said, according to a Reuters translation. They also had to pass particularly rigorous testing.
