The Reasons for Too Much or Too Less Foam in Flotation Tank


As one of the important mineral processing equipment, the flotation cell often meets the phenomenon

of unstable foam in the tank, such as too much and too big foam, too less and too small foam.

what is the reason for these problems?
Firstly, we should learn about the generation of foam in the tank.
The foam is created by injecting low-pressure air with an external tool, just as the bubble produced by inflating water with the pipe.
However, the foam produced by air inflation is not stable, and the quantity is uncertain. Therefore, using the foaming agent can increase the foam quantity and guarantee the stability of the foam.

So, what is the main reason for causing too much or too less foam in the flotation cell? That’s the foaming agent. In general, the excess dosage of foaming agent will cause too much and too large foam in the flotation tank, and even sometimes, the foam is too large to reflect light on the surface. On the contrary, the insufficient use of the foaming agent will cause too less and too small foam.

Then again, what is the effect of too much or too less foam on the flotation operation? If the foam is too large or too small, the amount of impurities will be too less, which cannot achieve the expected flotation efficiency. It not only affects the flotation effect, but also influence the final recovery rate.

Iron ore price rally could give BHP, Rio Tinto 30% earnings boost


Iron ore price rally could give BHP, Rio Tinto 30% earnings boost


Spot iron ore prices rose from $75 per tonne to $95 per tonne in the weeks following the Brumadinho dam disaster at Vale’s (NYSE: VALE) Feijao iron ore mine in Brazil, before settling in at about $85 per tonne, according to the latest research on the global iron ore market by the Macquarie Group.

Spot prices are now back up at the $95 per tonne level as lower shipment volumes out of Australia mainly due to Cyclone Veronica have contributed to supply disruptions from Brazil, analysts at the Australian investment bank and financial services company report.

In addition, premiums for high grade ore and discounts for lower grade ore have shrunk since the Brumadinho tragedy, Macquarie points out. Prices have risen by about 35% year-to-date for lower grade ore, while the premium for high grade ore has increased by 23% year to date.

Vale’s share of total shipments from Brazil has dropped to about 50% from a peak of about 90%, the report states. “While initially the quantum of decline was managed by the selling of stockpiles, recent sharp declines shows the extent of the supply disruption.”

The supply/demand dynamics benefit Australia’s iron ore miners.

“At spot prices all covered Australian iron ore miners see a substantial increase in forecast calendar year earnings per share,” the report stated. “BHP, Rio Tinto, and Mineral Resources Inc. see CY19 EPS increase by about 30% each, while the pure-play exposure is highlighted in Fortescue Metals Group and Mt. Gibson Iron as CY19 increases by 60% and 120% respectively in a spot scenario.”

Jaw Crusher Is One Indispensable Part In Mining

Jaw Crusher Is One Indispensable Part In Mining



Jaw crusher is one of the most popular equipment that being used for the primary crushing process, and it can be divided into the stationary jaw crusher and mobile jaw crusher. jaw crusher The application of the stationary jaw crusher is wider, which can be used to crush the following materials such as granite, marble, limestone, lignite, river pebbles, iron ores, copper ores.

This machine has the merits such as bigger crushing ratio, medium granularity, credible operation, lower production cost.

The prospect of jaw crusher in the mining field is bright, and the only thing that we can do now is to grasp the opportunity in order to occupy one important position in the international mining market. Owning the strong excellent technology to support the product' quality can become one significant advantage while competing with the other similar products. The future development orientation of jaw crusher is the green environmental protection and the lower-carbon, which can make a big difference to our surrounding living conditions. There still is one gap between the overseas designing level and our homemade, so our national jaw crusher manufacturers should pay much more attention to the R & D in order to improve the technological creation and to have the strong strength to compete with the international rivals.

How to adjust the ball mill temperature

How to adjust the ball mill temperature?

As we all know, the ball mill has high temperature requirements, and the temperature is very important for the equipment. How to adjust the temperature of the ball mill?

1. Improve ventilation
Strengthen the ventilation inside the ball mill and take away the excess heat inside the ball mill.
2.Reduce the temperature at which the material enters the mill
First of all, we must strengthen the inspection of the materials that need to enter the ball mill, avoid the high
temperature of the material directly into the water, and then spray the water on the material, and also spray the water on the belt of the clinker entering the ball mill.
3.Use special cooling equipment
The material is cooled by some cooling equipment, such as a cooler.
4.Increase grinding aid
We add some grinding aids to improve the internal adhesion of the ball mill to reduce the vicious cycle of high
temperature.

If the temperature is too high, it will affect the grinding effect. However, the ball mill can easily exceed the optimal
temperature during the operation. These measures can effectively improve the temperature of the ball mill and can well adjust the temperature required by the equipment. This is more conducive to the maximum efficiency of the equipment.
