    Mineral processing Wikipedia

    Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

    Trends in the Crushing of Mineral Ores Mineral Processing

    01/05/2016· Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.

    Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.

    Crushing and Pulverization of Ores Study Page

    Crushing and Pulverization of Ores. The ore is generally obtained as big rock pieces. These big lumps of the ore are crushed to smaller pieces by using jaw-crushers and grinders. The big lumps of the ore are brought in between the plates of a crusher forming a jaw. One of the plates of the crusher is stationary while the other moves to and fro and the crushed pieces are collected below. The

    Nickel / cobalt mining extraction procedures Industrial

    Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air

    Rock Crushing methods and How to recover gold from Ores

    No matter which crushing system you're using, the process will go far faster, and come out better if you do repeated screenings of the material from time to time. What happens in crushing is that some of the material gets crushed down to the size you want but other pieces don't. The small stuff then often gets in the way of the crushing process as you are working, basically protecting the

    Nickel: smelting, producing-Metalpedia

    In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and

    Energy Consumption in Mining Comminution

    Crushing is usually a dry process, and is performed in several stages, reduction ratios being small, ranging from three to six in each stage. The reduction ratio of a crushing stage can be defined as the ratio of maximum particle size entering to maximum particle size leaving the crusher, although other definitions are sometimes used. There are a number of crushers available such as jaw
