We also need more information when slurry concentration changes a lot or the material is highly abrasive or corrosive. Heavy magnetic loading and very tight recovery or concentrate-grade targets also need closer checking.<\/p><\/div>\r\n    <div class=\"cl-card cl-stop\"><h3>Choose Another Separator<\/h3><p>Use another separator for dry bulk feed or for aluminum and copper.

The target must respond strongly enough to a magnet, and it must be separated from the surrounding waste mineral. This is liberation. Next, we check how much slurry and magnetic material enter the drum and how the slurry moves through the tank. Only then do we fine-tune drum speed and magnetic settings.<\/p>\r\n  <div class=\"cl-grid-4\">\r\n    <div class=\"cl-card\"><h3>1. How Strongly the Material Responds to a Magnet<\/h3><p>If the target is only weakly magnetic, a larger drum will not make the wrong separator type work. The first step is to choose equipment with the right magnetic intensity.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>2. Whether the Magnetic Mineral Is Free<\/h3><p>If waste mineral is still locked to the magnetite, the separator may recover both. This unwanted material is often called gangue. If liberation is poor, stronger magnetics cannot replace grinding or classification.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>3. How Much Solid Material Enters the Drum<\/h3><p>We need slurry flow and the amount of solids in that slurry. This solids loading tells us much more than drum diameter alone.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>4. How Much Magnetic Material the Drum Must Carry<\/h3><p>A heavy magnetic fraction can overload the working zone and increase loss even when the magnetic field is strong enough.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>5. How Evenly the Feed Reaches the Drum<\/h3><p>If one side receives much more slurry than the other, part of the useful drum width is wasted and separation becomes uneven.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>6. How Slurry Moves Through the Tank<\/h3><p>Water level, flow direction, feed speed and discharge shape control how particles pass the magnetic zone. Engineers often call this tank hydraulics.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>7. Drum Speed<\/h3><p>Speed changes how long particles stay in the magnetic working area, how the magnetic layer moves and how captured material leaves the drum.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>8.

Wet Drum Magnetic Separator FAQ<\/h2>\r\n  <details><summary>What is a wet drum magnetic separator?<\/summary><p>A wet drum magnetic separator continuously separates a strongly magnetic fraction from slurry or pulp. A rotating drum carries captured magnetics to a separate discharge while the less-responsive fraction follows the tank flow.<\/p><\/details>\r\n  <details><summary>What is the difference between CTS, CTN and CTB?<\/summary><p>Do not choose a wet drum from the CTS, CTN or CTB letters alone. Different suppliers may use these model letters differently. We first choose how the slurry should move through the tank, then state the exact Corvelan model and tank arrangement on the quotation and drawing.<\/p><\/details>\r\n  <details><summary>How do I choose the tank-flow arrangement?<\/summary><p>Start with particle size, slurry concentration, magnetic loading and the result you need. We also check whether the magnetic mineral is fully liberated. A coarse recovery stage and a fine cleaning stage usually need different slurry-flow conditions.<\/p><\/details>\r\n  <details><summary>Is a wet drum suitable for magnetite <a href=\"https:\/\/www.corvelanmag.com\/applications\/iron-ore-separation\/\">iron ore<\/a>?<\/summary><p>Yes, when the magnetite is sufficiently liberated and the feed is slurry. We still check particle size, slurry concentration, magnetic loading and whether you need maximum recovery, cleaner concentrate or lower magnetic loss in tailings.<\/p><\/details>\r\n  <details><summary>Can a wet drum recover magnetite or ferrosilicon from dense-media circuits?<\/summary><p>Yes. Wet drums are commonly used to recover strongly magnetic magnetite or ferrosilicon medium. We size the separator from circulating-medium flow, solids concentration, contamination and how much magnetic medium is allowed to leave with the non-magnetic discharge.<\/p><\/details>\r\n  <details><summary>Why is magnetite being lost in the tailings?<\/summary><p>First check overload, changing slurry density, uneven feed and poor liberation. Also check how slurry is moving through the tank and the drum speed. If those conditions are correct but the separator is still overloaded, use more drum area or add another final recovery stage.<\/p><\/details>\r\n  <details><summary>Why is concentrate grade low even when recovery is high?<\/summary><p>First check whether waste mineral is still locked to the magnetite or whether slurry flow is carrying non-magnetic particles into the concentrate. If liberation is poor, improve grinding or classification. If liberation is already good, adjust slurry concentration, tank flow, rinse water or the cleaning stage before increasing magnetic intensity.<\/p><\/details>\r\n  <details><summary>Does higher Gauss always mean higher recovery?<\/summary><p>No. Gauss is a magnetic-field reading at a defined point. Recovery also depends on how strongly the material responds to a magnet and how well it is liberated. Slurry concentration, magnetic loading, tank flow, drum speed and discharge conditions also matter.<\/p><\/details>\r\n  <details><summary>What determines wet drum magnetic separator capacity?<\/summary><p>Capacity depends on slurry flow, solids throughput, solids concentration, particle size, magnetic loading, useful drum width, how slurry moves through the tank and the result you need. Drum diameter alone does not guarantee capacity.<\/p><\/details>\r\n  <details><summary>How many wet drum stages do I need?<\/summary><p>Use one stage when it can meet the recovery and product quality you need at the real operating load. Add a cleaner stage when concentrate quality is too low. Add a final recovery stage when too much magnetic material remains in the tailings. For medium recovery, add a second stage when one stage cannot keep medium loss low enough.<\/p><\/details>\r\n  <details><summary>Can the separator be fitted into an existing plant?<\/summary><p>Yes when the available footprint, feed elevation, discharge routes, support points, tank level, drive side and maintenance access allow the selected configuration. Send a line drawing or dimensions so we can place the interfaces correctly.<\/p><\/details>\r\n  <details><summary>How much does a wet drum magnetic separator cost?<\/summary><p>Price changes with drum size, useful width, tank design, magnetic system, drive, wear protection, controls, connections and the number of separation stages. Send the material, target, normal and peak throughput, and where the separator will work in your process so we can size the machine before quotation.<\/p><\/details>\r\n  <details><summary>What should I send for a wet drum quotation?<\/summary><p>Start with four items: material, target magnetic fraction, normal and peak throughput, and where the separator will work in your process. If available, also send particle-size distribution, slurry concentration or density, required recovery or concentrate grade, slurry chemistry or temperature, and a line drawing.<\/p><\/details>\r\n  <details><summary>What should a wet drum test report include?<\/summary><p>It should show the feed material, particle size, slurry concentration, feed condition, wet drum setup, drum speed, flow or solids throughput, sampling method, magnetic product, tailings and the result being calculated. A recovery or grade number without the operating conditions is not enough for a fair comparison.<\/p><\/details>\r\n  <details><summary>How should a Gauss reading be measured on a wet drum?<\/summary><p>State the measurement point, the distance or air gap from the drum, the instrument used and whether the drum is stopped or operating. Use the same method when comparing two readings. A Gauss reading describes the magnetic field at that condition; it does not by itself prove recovery or concentrate grade.<\/p><\/details>\r\n<\/div><\/section>\r\n\r\n<section class=\"cl-section\" id=\"rfq\"><div class=\"cl-inner\">\r\n  <div class=\"cl-kicker\">Get a Quote<\/div>\r\n  <h2>Send Four Things and We Can Start Sizing Your Wet Drum<\/h2>\r\n  <div class=\"cl-grid-4\">\r\n    <div class=\"cl-card\"><h3>Material<\/h3><p>Ore\/mineral or process medium, and whether the feed is slurry, pulp or dilute medium.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>Target<\/h3><p>The magnetic mineral, magnetite\/FeSi medium or magnetic contamination to recover or remove.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>Throughput<\/h3><p>Normal and peak solids throughput, or normal and peak slurry flow, plus solids concentration when available.<\/p><\/div>\r\n    <div class=\"cl-card\"><h3>Where It Works in Your Line<\/h3><p>Tell us whether it is the first recovery stage (rougher), a concentrate-cleaning stage (cleaner), a final recovery stage (scavenger), or a magnetic-medium recovery stage.
