Salt melts the ice. Even before it melts, though, the gritty salt melted pits roughen the ice, increasing friction.

Salt water has a higher freezing point. Therefore the ice melts if the temperature is close to 0 degrees Celsius. Caution is necessary you can end up with water over ice. Which is super slick.

The salt lowers the freezing point of the water--making it melt (usually). This is why when making ice cream, salt is added to the ice. The FP is lowered which causes it to melt and actually get "colder"--or lose more heat. Water on roadways and sidewalks is less slippery than ice...

Mmmm.... kay. Sounds like you just ruined your ice cream. Salty ice cream...yum yum! The salt is suposed to go on the ice around the pan. The salt causes the ice to melt more rapidly thus dropping the temperature around the canister which causes the mixture inside the canister to freeze... voila' ice cream!!! Dump that mess out and start all over again. The ice cream mix wont freeze because of the salt content in the mixture; thats why its been running for an hour and hasnt done anything!

the salt melts the ice, so its no longer slippery
