Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged ...

The ore crushing process includes four types: ore coarse crushing, ore medium crushing, ore fine crushing, and ore superfine crushing. Ore coarse crushing is a process of crushing ore blocks with a feeding particle size of 500–1500 mm to 125–400 mm. The maximum crushing ratio of coarse crushing is about three. The main force in the coarse ...

Konkola West Concentrator stockpile handles 55000 tonnes copper ore per day producing an average of 400 tonnes of concentrate. The grade of the concentrate is 36 to 40% TCu. The plant efficiency (recovery) is at 89% TCu. The concentrator operations include: Primary, secondary and tertiary crushing, grinding, flotation, dewatering and tailings disposal.

The ratio of −45 μm in −74 μm product decreases from 71.29% to 53.52% for untreated and treated ores and the inhibitory index is 0.24. The inhibitory effect for micro-fine particles can be effectively achieved by electrical pretreatment. ... Preferential sequence crushing of copper ore based upon high-voltage pulse technology. Miner. Eng ...

Section snippets Ore characteristics and preparation. The initial sample preparation was carried out and about 450 kg of both copper oxide and copper sulfide ore samples were prepared using a primary crusher.The crushing was done to achieve a similar feed particle size distribution for each crushing condition.

2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral processing (Spathis …

A typical copper ore-grade in open-pit mines is 0.5% and 1% or 2% in underground mines [43]. To extract the valuable metal, the processing route depends upon the type of ore. ... Reduction ratio (Rr) Crushing: Primary crusher: 264032: 175000: 2: Secondary crusher: 219797: 45000: 5: Grinding: SAG mill: 16145: 5000: 3: Ball mill: 1204: 145: 8: Re ...

For example, the effect of ore crushing on the shovels of the Gol-e-Gohar iron ore mine was presented with a mathematical model to determine their production levels. This model was obtained using data that differed from the shovels' production levels in different blasting patterns with different fragmentation results.

To feed a rod and/or ball milling circuit, you need to crush as follow: Crushers for large giant process plants >2,000 to 200,000 TPD using …

Copper mineral inclusions dispersed in crushed ore particles have a certain size distribution (grain-size distribution). For efficient heap leaching processes, the crushing plant should be designed and operated to crush the ore to an appropriate particle-size distribution so that copper mineral grains are exposed and can be leached.
