The best temperature is above 0℃. Resin should be put into a closed space or add in salt water of 5% or above if not used for a long time.Should be anti-freezing during transportation. Do not place heavy objects on the resin in case being crashed. Generally requires alkali- water - acid - water flow path for processing. Strict requirement needs three circulation before coming to final ion kenel. Need to consider different transformation expansion rate to set aside enough space to prevent resin overflow and ensure the appropriate liquid level height; Column diameter ratio should be within a reasonable range and avoid bias current; Use wet packed column or back-flushing to wash away bubbles inside resin layer. Before liquid going into the resin column, steps as flocculation, filtration, or sand-filtration should be taken so that it doesn’t jam resin pore with suspended solids . Resin inside the column that hasn’t been used for a long time should be storaged outside of the column after washing, or adding salt water in the salt resistant medium while keeping liquid level not dehydrated with usual backwashing to loosen resin in case of agglomeration.

Understanding How the Hydro Metallurgical Process of Extraction of Metals Is Based On At its core, the hydro metallurgical process of extraction of metals is based on using aqueous chemistry to liberate metals from their ores. It’s a fascinating and crucial technique allowing industries worldwide to recover valuable metals in an environmentally friendlier way than some older, harsher methods. Give
Understanding Cation Resin and Why It Matters Globally At first glance, cation resin might sound like something only chemists or water treatment specialists care about—but its impact is surprisingly broad. Essentially, this specialized resin plays a critical role in purifying water, treating industrial effluents, and even aiding in pharmaceutical and food industries. Globally, as water scarcity an
Understanding the Core of Hydrometallurgy The hydrometallurgy process represents a cornerstone of modern extractive metallurgy, providing sophisticated aqueous-based methodologies for recovering metals from diverse raw materials, including ores, concentrates, and increasingly, secondary waste streams. This discipline is lauded for its precision, adaptability, and generally lower environmental foot
Field Notes: Strong Base Anion Exchange Resin 201X7 FC If you work in demin plants, ultrapure water, or nitrate polishing, you’ve probably heard the term Strong Base Anion . Here’s a hands-on look at Liji’s 201X7 FC—polystyrene gel matrix with quaternary ammonium groups (-N(CH3)3)—that, to be honest, behaves like a “solid alkali” workhorse in mixed-bed lines. Made in Xingtai, Hebei (NO.2 East Jian
