摘要： A process for converting a copper sulphide matte and/or a copper sulphide concentrate to blister copper is described which comprises the steps of adding the matte and/or concentrate together with a suitable flux to an agitated molten bath containing molten slag phase and a molten metal phase; injecting by means of a submerged lance an oxidizing gas capable of reacting with the matte or concentrate to form a low sulphur blister copper phase, slag and sulphur dioxide; controlling the injection of the oxidizing gas such that a substantial portion of the gas contracts the blister copper phase; and separating blister copper from the bath. It is possible to obtain an amount of sulphur in the blister copper which is within a factor of two of the equilibrium value for a given percentage of copper in the slag.

摘要： A membrane for covering the cut end of a tree trunk to prevent the tree from creating a seal after it has been cut. The membrane is attachable to the cut end surface of the tree trunk and includes a hydrating layer comprising a hydrogel. The hydrogel, made up primarily of water, adheres to the cut end surface of the tree trunk to continue hydrating the tree, and prevents air from reaching the tree's exposed transport tissue. In some embodiments, the membrane includes a backing layer and a release layer on opposite sides of the hydrating layer.
