Project Description
Mining Defoamer | Foam Control for Mineral Processing & Flotation
Mineral processing and ore extraction operations face persistent foam disruptions across grinding, flotation, and tailing thickener circuits. Severe froth accumulation within froth flotation cells reduces concentration grades via gangue entrainment, induces slurry pump cavitation velocity restrictions, and creates extensive operational spill hazards across tailing pond lines. Managing these boundaries requires target active anti-foaming agents engineered stable across dense mineral slimes.
INVINO® synthesizes specialized polyether complexes and modified siloxane emulsions calibrated for fast macro-foam collapse and persistent micro-bubble de-aeration. Our chemistries control foaming without modifying the surface wetting characteristics of target minerals or interfering with xanthate/amine collector selectivity benchmarks.

Challenges of Foam in Mining and Mineral Processing
Persistent air entrainment generated during high-impact wet milling lines alters bulk pulp density parameters, reducing hydrocyclone classification sharpness thresholds and particle separation accuracy metrics.
Excessive macro-froth stabilization triggered by structural fatty acid or amine collectors induces gangue particle mechanical carryover, directly reducing concentrate recovery grades and inducing pump cavitation.
Entrained bubbles inside gravity thickeners retard solid slime settling acceleration rates. This compromises clear water overflow limits and lowers the dewatering output parameters of vacuum disc filters.
Strong acid or alkaline leaching loops generate proteinaceous foam headers that mask fluid contact interfaces. This delays extraction timelines and yields liquid containment overflows inside tailing ponds.

Technical FAQ for Mining & Beneficiation Operators
Q: Will the defoamer negatively affect the mineral recovery rate in Flotation?
A: No. Uncalibrated defoamers collapse the required mineralized froth layer indiscriminately, resulting in valuable mineral loss across tailings. INVINO-9128 is engineered utilizing block polyethers that lower excessive fluid surface tension fields while remaining entirely neutral to target sulfide/oxide mineral particle flotation selectivity parameters.
Q: Is it effective for Wet Process Phosphoric Acid (WPA) production?
A: Wet Process Phosphoric Acid requires specialized chemical formulations capable of surviving extreme hot sulfuric digestion boundaries (pH 1.0–2.0 up to 85°C parameters). For WPA digestion and gypsum filtration loops, operations should deploy our dedicated non-silicone compound series INVINO-P9502.
Q: Does your mining defoamer contain Silicone? (Silicon impact)
A: Traditional dimethyl siloxane emulsions carry phase-separation limits inside heavy electrolyte solutions, creating oil slicks that block ultrafiltration membranes or foul valuable mineral concentrates. Our mining series utilizes non-silicone hydrocarbons and structural polyethers to guarantee clean process limits.
Q: Can it be used in Wastewater Treatment and Tailings management?
A: Yes. INVINO-9128 provides strong surfactant knockdown properties that carry over effectively into gravity thickener overflows and tailing water recovery loops, accelerating mud settling rates without disrupting polymer flocculant bridging.
Q: What is the pH range stability of your mining defoamer?
A: Our chemical backbones maintain complete micelle integrity and persistent foam suppression capacities across wide processing boundaries, performing stable within extreme pH 3.0 to pH 12.0 operational windows.
Q: Where should we add the defoamer in the mineral circuit?
A: Dosing points must target high-turbulence blending nodes to optimize rapid dispersion boundaries. For flotation circuits, feed continuously straight into the conditioner tank inlet or the scavenger launder drop box via automatic diaphragm metering pumps.
