Chemical appearance: Copper sulfate monohydrate is usually greyish white in color. This is its state without any water molecules in it. When it absorbs some water, it turns to blue pentahydrate crystals or granules. Both types of copper sulphate have same chemical characteristics although they differ in color and their mass. The white powder does not have any odor but is toxic when ingested. Chemical application and strengths: The chemical is highly stable in neutral media and average room temperature. However, it is highly reactive with alkaline media where it decomposes and warms the alkaline material instead. The main use if the compound is a fungicidal spray on grapes, tea, coffee, cotton and cardamom. In rubber, it is sprayed from the above to control attack on the leaves. Copper sulfate is highly soluble in water and decomposes at high temperatures over 650 degrees Celsius. CAS Number:10257-54-2

Potassium Butyl Xanthate is a reagent that plays a pivotal role in modern mining and metallurgy. Flotation Process Facilitator: Potassium Butyl Xanthate is an indispensable ally in the flotation process, a cornerstone of mineral extraction. Flotation involves separating desired minerals from their ores. Selective Adhesion: When introduced to a slurry of finely ground ore and water, Potassium Butyl Xanthate selectively adheres to sulfide minerals present in the mixture. These minerals, often hosting valuable elements like copper or lead, exhibit a unique affinity for the xanthate. Bubble Attachment: Air bubbles are introduced into the slurry. The hydrophobic mineral surfaces coated with Potassium Butyl Xanthate collectors readily attach to the bubbles, effectively making them float to the surface. Rising to the Top: The mineral-laden bubbles rise to the surface of the flotation cell, forming a froth layer. CAS Number:871-58-9

The temperature of jacketed reactors can be controlled by TCUs (temperature control unit) large central heating/cooling units with secondary systems for individual reactor temperature control process steam (in case of large metal reactors) Our jacketed reactors are typically temperature controlled using heat transfer oil and TCU or central heating/cooling units.

In some cases, SIBX can emit a very faint unpleasant, or sulfurousodor. SIBX is readily soluble in water and could form insoluble compounds with different metallic ions. The uses of Sodium Isobutyl Xanthate (SIBX) as a collector are widely known. It is a credible flotation reagent for different nonferrous metallic sulfide ores. It is primarily implemented for the flotation of copper, lead, zinc sulfide ores as well as the sulfide ores of other precious metals. CAS Number:25306-75-6 HS Code:290519

Chemical appearance: Ferric alum appears as a white powder or crystalline. The crystalline and powder forms of the substance are soluble in water. However, it is not soluble in organic solvent such as ethanol. When in water, the solution appears clears and does not form a residue. Both of them are not toxic and do not catch flames. However, it can present an environmental hazard if spread in a large area. Chemical application and strengths: The compound contains trace amount of iron and lead and has a PH value of about 3.5. It can absorb water from the atmosphere; therefore, it should always be stored away from measures under a closed container. It should also be kept away from materials that may oxidize and lead to a darker color. Given that Ferric alum is powder that does not burn when it is exposed to fire, it is commonly used in firefighting foams. CAS Number:10043-01-3 HS Code:283322

Die Lödige-Schaufeltrockner sind diskontinuierlich arbeitende Vakuumtrockner. Das Schleuderwerk ist zur optimalen Prozessanpassung frequenzgeregelt. Durch spezielle, rotierende Mischelemente, eingebaut in einer zylindrischen, mit Temperiermantel versehenen Trommel, wird eine dreidimensionale Produktbewegung erzeugt. Die resultierende hohe Kontakthäufigkeit der Partikel mit der Wärmeaustauschfläche führt zu kürzesten Trocknungszeiten. Die Produktbewegung bewirkt einen intensiven Kontakt der einzelnen Produktpartikel mit der beheizten Behälterwand bei zugleich schonendster Behandlung des Produkts. Der optional verfügbare, hochtourig rotierende Messerkopf dient dem Produktaufschluss beim Phasenübergang . Dies führt zu einer deutlichen Erhöhung der Trocknungsleistung bzw. zur Vermeidung von Feuchte- und Temperaturgradienten. Mit den Lösungsmittelbrüden mitgerissene Feinpartikel werden im Filter abgeschieden und gelangen durch die pneumatische Filterreinigung zurück in das Produktbett.
