Methyl Isobutyl Carbinol, commonly known as MIBC, is a widely used mining frother for mineral processing and froth flotation. As a branched six-carbon alcohol, MIBC works at the air-water interface to reduce surface tension, control bubble formation, and support the separation of valuable minerals from gangue.
MYG MIBC mining frother produces fine, uniform, and controllable bubbles. The foam has sufficient stability to carry hydrophobic mineral particles to the froth layer while remaining relatively brittle, allowing it to break down more easily during concentrate handling and downstream processing.
With strong frothing capability and low inherent collecting power, MIBC is suitable for flotation circuits that require selective separation and controlled froth performance. The final dosage and reagent combination should be determined according to ore mineralogy, pulp conditions, flotation equipment, and recovery requirements.
MIBC helps reduce bubble coalescence and promotes the formation of smaller, more uniform bubbles. This supports stable froth coverage and improves the control of particle transport in the flotation cell.
MIBC mainly functions as a frother rather than a collector. Its low inherent collecting power helps reduce unnecessary recovery of gangue minerals and supports the production of higher-grade concentrates when properly matched with the collector system.
The foam generated by MIBC is fine and stable during flotation but relatively easy to break down after collection. This characteristic can help improve froth control and simplify concentrate handling.
MIBC can be used in flotation circuits for non-ferrous sulfide ores, selected oxide ores, and fine sulfide ores with a high slime content. It is commonly evaluated for copper, lead, zinc, molybdenum, copper-gold, and coal processing applications.

MIBC is primarily used as a frothing agent in mineral flotation. Its applications include:
Copper sulfide ore flotation
Lead and zinc ore flotation
Copper-molybdenum separation
Copper-gold flotation
Molybdenum mineral processing
Non-ferrous oxide ore flotation
Fine sulfide ore flotation with high slime content
Coal and other mineral processing applications
MIBC performance can vary according to ore properties, pulp density, pH value, water quality, aeration rate, impeller speed, and reagent dosage. Laboratory testing and plant trials are recommended before finalizing the flotation reagent scheme.
MIBC controls bubble formation and froth stability, while collectors help improve the hydrophobicity of target mineral particles. For this reason, MIBC is often used together with a suitable collector and modifier.
Depending on the ore and separation objective, MIBC may be combined with:
Xanthate Collectors, such as Sodium Isobutyl Xanthate and Sodium Amyl Xanthate
Dithiophosphate Collectors, including Dithiophosphate 25
Thiocarbamate Collectors, such as Isopropyl Ethyl Thionocarbamate
Flotation modifiers and depressants selected according to the mineral processing conditions
The correct reagent combination should be confirmed through mineralogical analysis, bench-scale testing, and flotation performance evaluation.
MYG MIBC mining frother is available in:
165kg iron drums
830kg IBC drums
These packaging options allow buyers to select a suitable format according to order quantity, transportation conditions, storage arrangements, and dosing equipment. Please confirm packaging, labeling, and shipping requirements before placing an order.
Yantai Junbang Beneficiation Materials Co., Ltd. is a manufacturer specializing in mining chemicals, including flotation frothers, xanthate collectors, dithiophosphate collectors, thiocarbamates, modifiers, and specialized reagents.
MYG supports product selection based on ore type, flotation process, pulp conditions, and target concentrate quality. Buyers can request product samples, technical documentation, and reagent recommendations before bulk purchasing.
MIBC mining frother is used to control bubble formation and froth stability in mineral flotation. It is commonly applied to copper, lead, zinc, molybdenum, copper-gold, and other mineral processing circuits.
MIBC is mainly a frother, not a primary collector. It helps form and stabilize bubbles, while collectors such as xanthate, dithiophosphate, and thiocarbamate make target mineral particles more hydrophobic.
The MIBC content is ≥89%. The product is supplied as a colorless transparent liquid.
The standard packaging options are 165kg iron drums and 830kg IBC drums.
Yes. MIBC can be used with xanthate collectors in suitable flotation circuits. The dosage and reagent ratio should be confirmed through laboratory testing and plant conditions.
Buyers should evaluate MIBC content, moisture, density, non-volatile matter, acidity, packaging, batch consistency, technical support, and sample test results before bulk purchase.
Tell us your ore type, flotation process, required MIBC content, packaging preference, and order quantity. MYG can provide a suitable MIBC mining frother solution for your mineral processing application.
