Which Metal Condenses On The Mountains Of Venus

They found that there is a lot of reflectivity from Venus's mountains peaks. So they suspect that instead of ice. Metal gas condendses on Venus's mountains, but which metal?

It is interesting, this has some nice pictures of the effect:

There are several metals that would evaporate gently at the 400 celcius on the surface and condense again at a lower temperature (lead for one - you are supposed to be careful about the vapour when you melt it), what confuses me is why they don't react with all the corrosive stuff in the atmosphere (SO2 H2SO4 etc) to form something that isn't reflective.

I think it is. The link claims "pyrite and tellurium" deposits. Both are metallic ores, not pure metals.
