Methods and system for recovering metals from combustion ash containing ferrous and nonferrous metals, including the steps of providing a feedstock source of ash, comminuting the ash to substantially reduce the particle size and liberate metal particles therein, separating the metal particles from the comminuted ash by particle size to obtain ash with a reduced metal content, at least one ferrous product and at least one nonferrous product.

The present invention relates to a technology for the production of porcelain stoneware products, wherein the treatment process allows to re-use recovery materials coming from the treatment of urban waste. In particular, the present invention relates to the production of products for the construction of driveways.

Disclosed is cylindrical ore washer for hydrometallurgical smelting of laterite nickel ore, comprising a mounting bracket, a screening component, a regulator, and an ore-washing component. The screening component comprises a frame, a cylinder body, a screening cylinder, and a driving component. The cylinder body is rotatably mounted on the frame along an axis oriented in a first direction. The screening cylinder is housed within the cylinder body, with a feed inlet and a discharge outlet located at opposite ends along the first direction, respectively. The cylindrical wall of the screening cylinder is provided with multiple screen holes, and an inner side wall of the screening cylinder protrudes to form a baffle plate. This disclosure is capable of impeding the movement of ore towards the discharge outlet, thereby prolonging the residence time of the ore within the screening cylinder and enhancing both the ore-washing efficiency and cleaning effectiveness.

A method for recovering metals from waste, in which the material is screened to produce a nonfibrous feedstock. The nonfibrous feedstock is then comminuted using a mill (e.g., a ball mill or rod mill) to liberate, flatten, and separate it, resulting in a mixture of a metal fraction and a residue. The metal fraction and residue are subsequently collected. A system employing this method is also described for treating such materials.
