Chrome ore is the imporant source of metal chromium and ferrochrome alloy. most chrome ore must be processed by the chrome ore processing plants. Chromite ore beneficiation machines are allocated according to the specific natures of the chrome ore. The main methods for chrome beneficiation are mainly gravity separation and magnetic separation.
Gold washing machine is developed for extracting gold from placer or alluvial gold deposit.
Placer/Alluvial gold deposit is secondary deposit,formed by weathering, river transport and deposition of primary gold, then deposit in low-lying area.This type of gold deposit contains much clay masses,gravel and free gold particle.
silicon manganese iron slag is the by-product during manufacturing the silicon manganese alloy，which is applied in the manufacture of virtually all types of steel and iron castings due to its desulfurizing and deoxidizing properties .
Aluminium ash and slag is the product of the molten slag produced in the electrolytic aluminium or casting aluminium process after cooling and processing.
Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 ◦C and its main components are SiO2, Al2O3 and MgO. Additionally it consists of chrome, ferrous/ferric oxides and Cao.The typical composition of the ferrochrome slags are 30% Si02, 23% MgO, 26% Al203 and 2% CaO.The chrome content in the slag is about 8% and the iron content 4% respectively.
