How can we use eco-friendly gold leaching reagent?

April 13, 2023 in /by

The method of using the eco-friendly gold leaching reagent is the same as that of sodium cyanide: Step 1: When using, the aqueous solution and pulp solution are first adjusted to be alkaline, and the pH of the solution is adjusted to 10-11； Step 2: During the entire leaching process, the alkalinity of the pulp […]

Why is coconut shell used in activated carbon?

April 10, 2023 in /by

Hello everyone, this is Michelle from Dasen Mining Machinery, today I wanna introduce coconut shell activated carbon for you. As we know, coconut shell activated carbon is made of high-quality coconut shells from Indonesia and Malaysia as raw materials, It is activated and finely processed by carbonization. Coconut shell-activated carbon is black in appearance, granular, […]

Do black sands in rivers have any value?

March 28, 2023 in /by

Coarse sand with few impurities (shells, silt, etc.) is a good sand. If you do a lot of engineering construction there, it will be valuable if it is convenient to transport.   How to refine the black sand in the river, and extract iron, titanium, and zinc? Firstly, beneficiation is to obtain titanium concentrate, iron […]

The river has gold, how can it be cleaned?

March 21, 2023 in /by

1. There must be gold in the river. Otherwise, there is no way to find it.2. If there is gold in the river, use the specific gravity of gold to far exceed the characteristics of sediment, wash away the sediment with water, and you will find gold. In order to extract gold from alluvial gold, […]

Does anyone know what black sand is? What is its value?

March 16, 2023 in /by

In general, it is some fine powder of iron or other metal substances that can be sucked up with a magnet. In the sand and gravel factory, most of the placer gold is washed out as fine black sand. It is only through the special appraisal of the technical department that I can determine the […]

The process of flotation is affected by a number of factors

March 7, 2023 in /by

Many factors affect flotation, including grinding fineness, pulp concentration, flotation time, reagent system, pulp temperature, flotation process, water quality, and flotation equipment type. Flotation fineness requirements (flotation particle size) In the flotation process, the flotation particle size is closely related to the sorting index. The adhesion of ore particles and air bubbles is the basic […]

What is the secret to beneficiation spiral chutes?

February 21, 2023 in /by

Mineral processing has long used spiral chutes as a technology. It combines the characteristics of a shaking table and centrifugal concentrator, making it the best equipment for mining and mineral processing, especially for placer mining on seashores, riversides, sand beaches and streams. for the ideal. However, the old equipment also has its technical limitations. As […]

Spodumene is processed by experiment for lithium extraction

February 15, 2023 in /by

Spodumene can be beneficiated from hand selection and flotation. Positive flotation and reverse flotation are flotation methods. Positive flotation is a common method. After high concentrations, strong stirring, multiple washings and deslimings of sodium hydroxide or sodium carbonate pulp, adding fatty acids (such as oleic acid) as collectors to directly float spodumene, it is possible […]

When using cyanide, how can you be sure that it is safe and effective?

January 10, 2023 in /by

In this article, we provide a brief overview of the use of cyanide in the recovery of gold from ores. While the use of cyanide is critical to the modern gold mining industry, Omori understands the concerns about the use of this sodium cyanide reagent for gold extraction and through this discussion provides information on […]

A separation and enrichment method for spodumene and beryl dressings

January 9, 2023 in /by

Both spodumene and beryl are aluminosilicate minerals, which often coexist in the same pegmatite deposit; because their minerals are non-magnetic, and their relative densities are close, and are similar to those of gangue minerals. Therefore, it is difficult to separate beryl and spodumene by magnetic separation and gravity separation, and only by flotation separation. On […]
