I was working Local Control. There were strong crosswinds. I had 2 aircraft on final and a departure from the east side westbound. Second arrival declared a go-around. I instructed them to climb to 9000 feet and track the Localizer. Then the first arrival declares a go-around; less than 3 miles ahead of the 2nd aircraft. I climbed the first aircraft to 6000 feet because the second one is at 6400 feet and 200 knots faster. Local East coordinates with me that he'll issue his aircraft a 280 heading behind my 2 on a 260 heading once I get them separated.I give the second aircraft a turn to the west heading 270 to get it started trying to stay away from the higher MVA (Minimum Vectoring Altitude). I had separation but never climbed the first go-around aircraft and gave them a turn to the west heading 260. Then the supervisor tells me the second aircraft is going to Departure Control at 9000 feet heading 260 and the first aircraft is approved heading 280 to Departure Control at 9000 feet. Trying to figure out where the west bound turn from the East side is going the first go around entered an MVA of 7000 feet at 6000 feet with instructions to climb to 9000 feet. I asked if he could maintain his own terrain clearance he replied yes prior to entering the MVA.There should be more TRACON training to give adequate speed and spacing especially in nasty weather. There should have been less supervisor coordination when controllers have already worked things out. No one is ever on the same page.
SLC Local Controller reported sudden wind shifts to a crosswind caused simultaneous go-arounds and one aircraft below the MVA.
