Placer deposits are formed by the mechanical concentration of resistate minerals, which are released by weathering from source rocks in which their distribution is normally subeconomic. The main commodities derived from placer deposits are tin, gold, platinum, niobium, tantalum, titanium, zircon and diamonds. Some metals, such as gold; occur within the

The placement problem has become more complex and challenging due to a wide variety of complicated constraints imposed by modern process technologies. Some of the most challenging constraints and objectives were highlighted during the most recent ACM/IEEE International Symposium on Physical Design (ISPD) contests.
