What is nonionic powder flocculants / polyacrylamides (ndpam)?

Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.

Why are nonionic polyacrylamides used in mining?

Nonionic polyacrylamides are used, among other things, in mining to improve throughput, enhance yield and optimize processes especially where low pH conditions are involved. Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs.

Can polyacrylamide polymers be used for flocculation?

Protein design for flocculation Synthetic polyacrylamide polymers currently used are generally effective as flocculants fine particles in the size range about 10–100 μm. However, they are not specifically designed for the purpose of flocculating ultra-fine (<10 μm) and clay particles which require higher dose of the polymer.

What is a flocculant used for?

To address issues with mining waste, flocculants are often used to separate water from solid mineral particles such as clay by enhancing the sedimentation rate . A flocculant, typically a high molecular weight polymer, is added to a suspension to bind particles together.

What is flocculation in mining waste management?

Introduction Flocculation, the aggregation of ultra-fine particles, is crucial to current mining waste management and is a standard method for dewatering tailings . To address issues with mining waste, flocculants are often used to separate water from solid mineral particles such as clay by enhancing the sedimentation rate .

Why do mining sites use flocculants?

As more minerals are extracted, the use of water increases, leading to greater wastewater and tailings production. To tackle this issue, flocculants are commonly used across mining sites to dewater waste streams by binding and settling particles, to allow for improved solid-liquid separation.
