The HCT thickeners are proven to provide the best washing efficiency, thus reducing the loss of nickel metal in leaching residue," says Markku Teräsvasara, President, Minerals and Deputy CEO of Outotec.
hardness of the ore and the ore feed size required for the grinding mill. Rod mills and balls accept ore crushed to less than 1 to 1-1/2 inches, and autogenous and semi-autogenous mills (where the ore acts as all or part of the grinding media) can accept ore as coarse as 6 inches in diameter. Grinding is usually done wet using recycled

Small Wet Ore Grinding Ball Mill Gold Mining Machine Extraction Equipment Working Principle The transmission device drives the cylinder to rotate. Materials and water are fed from the feeding end of the cylinder. Ores are ground into fine particles by the grinding of steel rods, as well as the impact & grinding of ores themselves.
Outotec has won a contract for a fleet of horizontal grinding mills and thickeners to a greenfield nickel project in Indonesia. The company said the machinery is worth approximately $27.8 million (€24 million), and it has been booked in its Minerals' Q3/2021. Details of …
Description: Prater Fine Grinders (M Series Mills) are designed to grind dry, free-flowing material as fine as 200 mesh (75 microns) with very tight distribution of particle size. The highly efficient design allows for ease of access to all internals and is well suited for heat sensitive materials such as Equipment Types: Hammer / Cage Mill
Type 316 contains slightly more nickel than Type 304, and 2-3% molybdenum giving it better resistance to corrosion than Type 304, especially in chloride environments that tend to cause pitting. Type 316 was developed for use in sulfite pulp mills because it resists sulfuric acid compounds. Its use has been broadened, however, to handling

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding
An autogenous mill of ID 6.7. m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20% of its volume.. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed.The solids in the mill charge were at 80% solids. Estimate:1. The power consumption per tonne per day.
