Carefully pass the magnet over the black sand from about a half inch above the black sand concentrates. On this first pass, do not touch or stir the concentrates with the magnet. The trick is to make the magnetite and hematite jump up through the water to the magnet leaving the gold behind.

placer or "black sand" deposits around the world are known for their economic concentrations of heavy minerals such as monazite, zircon, ilmenite, rutile,
It is one of several oxides of iron and has strong magnetic properties. Magnetite is a significant ore of iron and as such, is distinguished from other ores of iron by its tendency to attract and get attracted to magnets. Before we jump towards discussing magnetite uses, let's take a closer look at magnetite itself.
Sand comes in many colors, thanks to various minerals mixed in among the grains. The black sand here contains magnetite, a form of iron. Photo courtesy of Kate Hintz, SMM
Octahedral crystals are a common habit of magnetite. They are often seen in igneous and metamorphic rocks and sometimes seen in sediments near the magnetite source area. The magnetite crystals in this photo are about eight to twelve millimeters in maximum dimension. Banded sand with the magnetite and other heavy minerals in quartz sand. Chennai, India.

Black sand or magnetite mining is being done now in almost every part of the country. In Cagayan, this is an ongoing problem, with both small scale and large scale miners coming in to gather black sand from both on and offshore.
This black sand is mainly composed of ilmenite, magnetite, garnet, zircon and rutile. Also present, in minor or trace amounts, are quartz, sphene, pyroxenes, sillimanite, feldspars, biotite, haematite, tourmaline, chromite, niobianrutile and pyrrhotite. Niobianrutile and pyrrhotite were found as inclusions in ilmenite and magnetite respectively.
A sample of black magnetic sand was collected on the northern sea shore of Ladispoli, near the medieval ruins of Torre Flavia. The sand is composed of regular smooth edged grains with dimensions around 200 µm. The mate rial is highly magnetic, as shown in . Figure 1. For the XRD and EDS analyses, magnetic grains were separated
Abstract. Samples of the littoral and alluvial placer deposits of the black sand concentrates which contain radioactive resistate minerals were collected from various parts of South India and their characters with respect to colour, density and radioactivity were presented. With the aid of a hand magnet and a sensitive Frantz Isodynamic laboratory...
Iron and titaniumbearing oxides – the "black sand" minerals. It is less common in placer concentrates than the iron oxides but it is tough mineral and can be present in at least trace amounts. Chromite is ironchrome oxide. It forms small equant black grains, is not magnetic, and has a resinous to metallic luster.
