LATEST Differences Between CIL and CIP Gold Extraction

Carbon In Leach (CIL) and Carbon In Pulp (CIP) are two commonly used methods in the gold extraction process. Although both methods involve the use of activated carbon to adsorb gold, there are significant differences in their operation processes, equipment layout, and application conditions. This article will explore the differences between CIL and CIP, highlighting their respective advantages, disadvantages.

1. Basic Principles

1.1 Carbon In Leach (CIL)

The Carbon In Leach (CIL) process involves adding activated carbon directly into the leaching tanks where both leaching and adsorption occur simultaneously. The CIL process includes the following steps:

  • Crushing and grinding the gold ore into a pulp.

  • Mixing the pulp with sodium cyanide solution to dissolve the gold into a cyanide complex.

  • Adding activated carbon to the pulp during the leaching process, where the activated carbon adsorbs the dissolved gold.

  • After leaching and adsorption, the pulp undergoes solid-liquid separation to recover the gold-laden activated carbon.

  • The gold-laden activated carbon undergoes desorption and electrolysis to recover the gold.

1.2 Carbon In Pulp (CIP)

  • The Carbon In Pulp (CIP) process differs primarily in the timing of adding activated carbon. The CIP process includes:

  • Crushing and grinding the gold ore into a pulp.

  • Mixing the pulp with sodium cyanide solution to dissolve the gold into a cyanide complex.

  • After leaching, transferring the pulp to a series of adsorption tanks where activated carbon is sequentially added to adsorb the dissolved gold.

  • After adsorption, the pulp undergoes solid-liquid separation to recover the gold-laden activated carbon.

  • The gold-laden activated carbon undergoes desorption and electrolysis to recover the gold.

2. Main Differences

2.1 Process Differences

Simultaneous Leaching and Adsorption: In CIL, leaching and adsorption occur simultaneously in the same step, whereas in CIP, leaching occurs first, followed by adsorption.

Process Complexity: CIP has a relatively simpler process because leaching and adsorption are separate steps. CIL requires more precise control of process parameters as leaching and adsorption occur concurrently, making it more complex to operate.

2.2 Equipment Configuration

CIL: Since leaching and adsorption occur in the same tank, CIL requires fewer tanks, but each tank is larger and more complex in design.

CIP: CIP requires separate leaching and adsorption tanks. Although there are more tanks, each tank is simpler in design and offers greater operational flexibility.

2.3 Gold Ore Characteristics

Ore Type Suitability: CIL is more suitable for low-grade, high-clay-content ores as these ores can clog the leaching tanks during processing. CIL’s design can better handle this issue. CIP is more suitable for high-grade, uniformly sized ores.

Pulp Handling Capacity: CIL requires stricter control over pulp concentration and particle size, while CIP is relatively more forgiving.

3. Advantages and Disadvantages

3.1 CIL Advantages and Disadvantages

Advantages:

Simultaneous leaching and adsorption result in a shorter process with faster reaction times.

Better suited for high-clay-content ores.

Disadvantages:

Requires precise control of leaching and adsorption process parameters, making it complex to operate.

Higher initial investment due to more demanding equipment and process design.

3.2 CIP Advantages and Disadvantages

Advantages:

Simple process with high operational flexibility.

Adsorption tanks can be used in series, improving adsorption efficiency.

Suitable for high-grade gold ores with simpler process control.

Disadvantages:

Requires separate leaching and adsorption tanks, occupying more space.

Less effective for high-clay-content ores.

Talc grinding process steps

Talc powder production is generally divided into four types: talc coarse powder processing (0-3mm), fine powder processing (20-400 mesh), and ultrafine powder processing (400-1250 mesh) and micro-powder processing (1250 mesh — 3250 mesh).

The first stage: crushing of raw materials

The bulk talc material is broken by the crusher to the feeding fineness (15mm-50mm) that can enter the grinding machine.

The second stage: grinding

The small pieces of broken talc material are sent to the storage hopper by the elevator, and then are uniformly and quantitatively sent to the grinding room of the mill by the feeder.

The third stage: grading

The material after grinding is graded by the classification system, and the unqualified powder is graded by the classifier and returned to the main machine for re-grinding.

Stage 4: Collection of finished products

The powder conforming to the fineness enters the dust collector with the air flow through the pipeline for separation and collection. The collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then is uniformly packed by the powder filling tank truck or automatic baler.

Calcium Carbonate Manufacturing Process and Equipment

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite, and it is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate has a variety of uses, including in the production of building materials, as a filler in plastics and coatings, and as a dietary supplement.



The manufacturing process for calcium carbonate involves several steps:

Quarrying: Calcium carbonate is extracted from the ground using a variety of methods, including open-pit mining, underground mining, and quarrying. The material is typically found in limestone, chalk, or marble deposits.

Crushing and grinding: Once the raw material has been extracted, it is crushed and ground into a fine powder. This powder is then transported to a processing plant.

Purification: The powder is purified to remove impurities such as silica, iron, and aluminum. This is typically done using a combination of chemical and physical processes.

Precipitation: The purified powder is mixed with water and a chemical called soda ash (sodium carbonate) to create a slurry. Carbon dioxide gas is then bubbled through the slurry, causing the calcium carbonate to precipitate out of the solution.

Drying and packaging: The precipitated calcium carbonate is then dried and milled to create a fine powder. The powder is then packaged and shipped to customers.

Equipment used in the manufacturing process includes:

Crushers: These are used to crush the raw material into smaller pieces.

Grinding mills: These are used to grind the raw material into a fine powder.

Classifiers: These are used to separate the powder into different particle sizes.

Mixers: These are used to mix the powder with water and other chemicals.

Reactors: These are used to mix the powder with soda ash and carbon dioxide to precipitate the calcium carbonate.

Dryers: These are used to dry the precipitated calcium carbonate.

What is the difference between light and heavy calcium carbonate?

Calcium carbonate (CaCO3) is a chemical compound that exists in different forms, including two main crystal structures: calcite and aragonite. The difference between light and heavy calcium carbonate is primarily based on their particle size and density.

Light calcium carbonate, also known as precipitated calcium carbonate (PCC), is produced through a chemical reaction in which limestone (calcium carbonate) is dissolved in acid, and then re-precipitated using a precipitation agent. The resulting product has a smaller particle size and lower density compared to heavy calcium carbonate, making it ideal for use in applications that require a fine particle size, such as in paper coatings, plastics, and rubber.

On the other hand, heavy calcium carbonate, also known as ground calcium carbonate (GCC), is produced by grinding and milling limestone. The resulting product has a larger particle size and higher density than PCC, making it suitable for use in applications that require a coarser particle size, such as in construction materials like concrete and mortar.

In summary, the primary difference between light and heavy calcium carbonate is their particle size and density, which determine their suitability for specific applications.
