<p>The present invention relates to a recycling method for a rare earth mineral used as a primary material to manufacture medical products, namely dental prosthetics. A block recycling method to recycle a waste zirconia block to form a partially stabilized zirconia block is disclosed. More specifically, after a partially stabilized zirconia block which is formed from rare mineral is used, the block recycling method recycles the zirconia block which is conventionally discarded. The block recycling method requires minimal expenses to recycle the zirconia block, and can manufacture an inexpensive recycled zirconia block having the same effectiveness and functions as an expensive zirconia block.</p> |
