PRIMARY CRUSHER SELECTION CRITERIA • Will it produce the desired product size at required capacity • Will it accept the largest feed size expected • What is the capacity to handle peak loads • Will it choke or plug • Is the crusher suited to the type of crushing plant design • Is the crusher suited for underground or in-pit duty
They contain proven and probable reserves of 3.3 million oz. of gold in 155 million tonnes of ore with a grade of 0.65 g/t gold for 3.2 million contained oz. The Eagle mine produced 164,222 oz. of gold in 2021. The company is also working on what it calls Project 2040, which would extend the life of the mine by 10 years to 2040.
DOVE is a major manufacturer of Hard rock Gold mining equipment, crushing plants, and portable Hard rock mining equipment for recovery of Gold, Platinum, Silver, Manganese, Zinc, Nickel, Tin, Lead, Zircon and other metals contained in hard rock deposits (Primary deposits) and quartz rocks.
Crushing plant feed material, with a maximum top size of 1,000 mm, is trucked from the open pits and dumped directly into the primary gyratory crusher at a throughput of approximately 29,500 t/d. The primary crusher will operate 365 d/a, while the secondary and tertiary crushers will only operate 275 d/a when ore is stacked on the HLPs.
The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant.

- good recovery even for fine gold (if properly built and operated)
Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
8 Construction, Working and Maintenance of Crushers for Crushing Bulk Materials www.practicalmaintenance.net Gyratory Crushers Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks.
Sandvik has applied an innovative 3D methodology to conduct design work on a new crushing plant at Randgold Resources’ Gounkoto mine in Mali. The project entails the crushing of the primary ROM gold ore and transporting it to a secondary crushing station to be stacked by a slewing stacker. Sandvik Mining Systems was awarded the contract in
Metallurgical testing has shown that primary crushing will increase both the overall gold recovery and the rate of gold recovery. At the present ore mining rate of 14,000 tons per day, the crushing circuit will produce an estimated 6,000-7,000 additional gold ounces per year. Technical Disclosure
In the primary crushing stage, the ore is normally crushed as soon as possible after its arrival. Many underground mines have primary crushers underground to reduce ore size and improve hoisting efficiency. Skips, trucks, and other handling vehicles are intermittent in arrival, whereas the crushing section, once started, calls for steady feed.

Jaw Crusher is one of the main types of primary crushers in a mine or ore processing crusher plant and also is one of the most widely used crushing equipment in mining industry. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even.
Primary crushing as a unit operation serves mining operations to maximize load and haul equipment utilization and milling operations as a comminution step. Many mines select primary crushers based on top size of the designed or anticipated ROM ore. This can result in a substantial excess of primary-crushing capacity for smaller operations.
The process plant is a conventional gold processing circuit with crushing, grinding, leach and gold recovery steps to produce gold Dore at site. Ore grade is upgraded in the crushing circuit via dual laser ore sorting. Scope of work highlights include: A 3- stage modular crushing and screening circuit operating at a minimum of 400,000 tpa.
