求翻译：将重矿物薄薄地铺在玻璃板上，用薄纸包住Nd-Fe-B型磁铁在矿物薄层上缓慢移动，反复多次将磁性矿物完全吸出后，将分离出的磁性矿物和无磁性矿物分别称重，放入样品袋中备用。是什么意思？

Thin ground floor of the heavy minerals in the glass, nd-fe-b magnet in the mineral thin layer of slow-moving tissue paper wrap, repeated magnetic mineral is completely sucked out, it will isolate the magnetic minerals and magnetic The mineral was weighed into the sample bag for use.

The heavy minerals to thin out the glass, wrapped in tissue B Nd - Fe - thin-magnet in the minerals on repeatedly, slowly move the magnetic minerals completely out, will be the magnetic mineral and non-magnetic mineral weighed separately and place in the sample bag.

The heavy mineral light makeshift bed on the ground on the glass plate, wraps up the Nd-Fe-B magnet with the flimsy in the mineral thin layer the slow migration, after repeatedly many times the attractive mineral complete aspiration, the attractive mineral and a nonmagnetic mineral minute alternate

Heavy minerals on thin ground floor shops in glass, with tissue paper wrap Nd-Fe-B-magnet on the thin-layer mineral moved slowly repeated after you completely sucked out of magnetic minerals, separation of magnetic minerals and non-magnetic minerals weighed separately, in a sample bag stand.
