When dropping the bar, most important is to make sure no stuff is lying around on the platform, and to keep the wrists behind the bar at all times. If dropped from chest height the bounce will usually be controllable.
Allthough dropping the weights is nice, lowering them under control is also nice. With correct technique for lowering the weights, dropping the bar can be saved for failed and near maximum attempts. With powercleans, the best way to lower the weight is to do more or less a reverse power clean. Start by going into a quarter squat, then quickly lower the elbows to let the weight fall off your shoulders, and at the same time extend the body and go up on your toes. When you are in full extension with straight arms you deaccelerate the weight with your legs and back while following it down, so you end up in something like the start position of a hang clean. Basically the same movement as a powerclean, but in reverse order.
Personally I find it easier to lower the bar after a powerclean if I do it just a split second after catching it, with no pause.
