    DOVE Semi-stationary Hard Rock Plants unique designs are embedded in every single one of their components to insure efficient operations and 100% recovery of the Gold, Tin, Iron, Tantalite, Manganese and other metals and minerals production, with no loss.

    Ore feeding, Crushing (Coarse and Fine), Grinding (or milling), Sizing (screening and classification) and Concentration (separation and recovery) are the three most important steps that are involved in ore processing by Hard Rock Plants. Overlooking any short of these steps will result in lack or reduction of recovery, as well as the loss of the valuable minerals.


    GOLDROCKMINER®  Hard Rock Plant

    In a hard rock plant, the concentration (recovery and separation) stage is achieved by a method scientifically called “Gravity Separation”. The separation occurs when the metals and mineral are subjected to a variety of forces in a medium (e.g. water, air, other heavy medium) to trigger a response, which is usually enhanced resistance or accelerated settling time of said metals and minerals, depending on their specific gravity.

    The major components of DOVE Semi-stationary Hard Rock Plants are as below:



    consists of a large hopper designed to feed the ore to the rest of the hard rock plant. The hopper, in a hard rock process, usually allows for dry feed of the rocks to the plant. It is designed for a direct feed by earth moving equipment. The size of the feed will depend on the plant’s capacity (TPH).

    DOVE Ore Feed Hoppers are supplied in wide range of capacities, and are designed and engineered as parts that fit to make the hopper. This feature allows the hopper to easily be shipped in standard containers and rapidly be assembled and installed once on site.

    DOVE Ore Feed Hoppers are built with thick and heavy sides that provides strength and endurance to the severe conditions of the mining site.

    it is a device set between the hopper and belt conveyor, or any equipment fed by the hopper. This device will ensure that the material coming from the feed hopper is efficiently and smoothly fed to the next equipment. The vibrating feeder prevents the hopper from being clogged by the accumulation of rocks and allows the next equipment to be safely fed without having to endure the stress of rocks falling directly on it, which could accelerate wear and tear, and result in damage.

    DOVE Feeders are a wide variety of vibrating feeders that can be configured with grizzly bars to screen the oversized rocks contained in the ore to ensure efficient processing and recovery of the minerals in the next stages, and to protect the next equipment from the potential damages that could occur from an impact with said rock. The screening sizes vary depending on the ore characteristics and project specifications.

    Because of their strong build, DOVE Feeders have a proven history of optimal efficiency and durability, even when handling large rocks.

    is a device designed to reduce rocks into smaller rocks or dust. It operates using a mantle that rotates within a bowl. The material is compressed between an eccentrically rotating piece of steel, called the mantle, and a stationary piece of steel, called the bowl. The material works its way down along the crushing chamber, as it gets smaller, until the crushed material is discharged at the bottom of the machine.

    DOVE Cone Crushers are designed to handle various capacities and material hardness, in secondary and tertiary crushing operations, for limestone, granite, basalt, quartzite, river gravel, and many more. DOVE Cone Crushers are designed for rapid Field Adjustment and Continuous Lubrication. They are configured with Hydraulic Cleaning units and Hydraulic Lifting Arm.

    are a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.

    Gold centrifugal concentrators have been developed over the past century and allow for mining operations to trap a higher percentage of the fine gold and other precious metals in black sands that used to be lost into the tailing ponds. Centrifugal gold concentrators operate using G-forces, which allow for separation of the heavier particulate including fine gold and other metals.

    DOVE Centrifugal Concentrators are configured for automatic and continuous recovery, using only recycled water to process and to recover 100%, down to 40 microns (0.004 mm), of all fine the gold, silver, platinum group metals, and other precious metals contained in the processed ore.

    DOVE Gold Concentrators are integrated with a complete hydraulic system, as well as feed and moisture adjustment mechanism, to eliminate freezing conditions and regulate the flow of the material.
