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.

Loparite in placers of the Lovozero placer cluster on the example of the Sergevan site
Геология рудных месторожденийLoparite is the main placer-forming mineral in placers located along the periphery of the Lovozero alkaline massif. The article presents new materials for the study of loparite from samples taken during field work at the Sergevan site of the Revda placer, located near the northern frame of the massif.
